Add SDIO ids for use with the muRata 1YN (Cypress CYW43439).
The odd thing about this is that the previous 1YN populated
on M.2 card for evaluation purposes had BRCM SDIO vendor ID,
while the chip populated on real hardware has a Cypress one.
The device ID also differs between the two devices. But they
are both 43439 otherwise, so add the IDs for both.
On-device 1YN (43439), the new one, chip label reads "1YN":
```
/sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device
0x04b4
0xbd3d
```
EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4":
```
/sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device
0x02d0
0xa9a6
```

These tables contain BB and RF parameters that driver will load them into
registers. It also contains TX power according to country, band, rate and
so on. Increasing thermal can cause TX power degraded, so power tracking
tables are defined to compensate TX power.
Internal version of these tables:

One chip can have different RFE (RF front end) types which we will judge
at runtime. And, different RFE types may use different RF parameter tables.
Though we didn't really meet this case previously, we are going to meet it
on upcoming chip RTL8851B. So, this commit handles parameter tables for
runtime RFE type.
We now encapsulate rtw89_txpwr_rule_<2/5/6>ghz tables into rtw89_rfe_parms.
Then, each chip defines its default parameter tables, and if needed, it can
configure extra parameter tables by RFE type. Finally we determine runtime
parameter tables by RFE type if one is configured. Otherwise, we use the
default parameter tables.
For now, we just move all settings under default parameter tables. We will
configure parameter tables by RFE types in separate commits afterwards.

In the discuss threads [1] [2], new firmware format break user space
because older drivers can't recognize new firmware format. To avoid this,
the new format will be named rtw89/rtw8852b_fw-1.bin and only new driver
try to load it. Old drivers only load original and understandable firmware
rtw89/rtw8852b_fw.bin.
More, new driver will be still backward compatible with old firmware, so
original firmware can be used by new driver.
If there is newer firmware format is introduced, rtw89/rtw8852b_fw-2.bin
will be given. The same rules will be applied like above. So, we will have
firmware like below in linux-firmware in the future.
rtw89/rtw8852b_fw-2.bin
rtw89/rtw8852b_fw-1.bin
rtw89/rtw8852b_fw.bin
After this patch, MODULE_FIRMWARE() of 8852A/B/C become
rtw89/rtw8852a_fw.bin
rtw89/rtw8852b_fw-1.bin
rtw89/rtw8852c_fw.bin

Since we are going to load more than one firmware and some are not
presented or optional, using asynchronous API request_firmware_nowait()
will become complicated. Also, we want to use firmware_request_nowarn()
to avoid warning messages when loading optional files. So, use
schedule_work to be simpler.
To abstract loading a firmware or file, define a struct rtw89_fw_req_info
containing a struct firmware and a completion to ensure this firmware is
loaded completely.

In early feature bitmap obtained from rtw89_early_fw_feature_recognize(),
the bits needed to check get increased. It's more friendly to work with
RTW89_CHK_FW_FEATURE(). So, we concentrate the flow of iterating FW feature
configures and calling RTW89_SET_FW_FEATURE() for various uses. And then,
we adjust rtw89_early_fw_feature_recognize() for RTW89_CHK_FW_FEATURE().

We used to store operating channel info after associated. However, scan
might happen before that. Without switching back to operating channel,
authentication or association might fail. Therefore, we switch back to
operating channel when the scanning vif's BSSID is non-zero, which
implies connected or during attempt to connect.

Use POWER_ON flag to make sure power on/off is symmetric. Since both
remain_on_channel and hw_scan both alter the power state, this makes
sure that we don't enter/leave IPS mode twice.
Also, replace IPS related functions with inline function that does
similar logic so we can track it more easily.

Add support of remain on channel ops. Since channel context is
required to enable multi-channel concurrent(MCC) and the current
ROC in mac80211 don't support more than 1 channel context, add this
to let P2P and other protocols relying on this work as expected.
The off-channel duration and cancel timing is purely controlled by
upper layers.

Allocate a per-skb completion to track those skbs we are interested in
and wait for them to complete transmission with TX status.
Normally, the completion object is freed by wait side, but it could be
timeout result that complete side should free the object instead. Add a
owner field with RCU to determine which side should free the object.

monitoring and beacon processing, then notify driver upon signal
changes or beacon loss.

The setting of the rate used for non station cases did not take into
consideration the interface type etc., thus when probe responses
are transmitted on P2P Device interface etc. CCK rates were used
which is not allowed.
Modify the code so the non station case would consider the
interface type etc. For HWs/FWs that do not support rate control,
preserve the previous behavior, i.e., take the rate from the
skb metadata and adjust as needed.

An integer overflow occurs in the iwl_write_to_user_buf() function,
which is called by the iwl_dbgfs_monitor_data_read() function.
static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count,
void *buf, ssize_t *size,
ssize_t *bytes_copied)
{
int buf_size_left = count - *bytes_copied;
buf_size_left = buf_size_left - (buf_size_left % sizeof(u32));
if (*size > buf_size_left)
*size = buf_size_left;
If the user passes a SIZE_MAX value to the "ssize_t count" parameter,
the ssize_t count parameter is assigned to "int buf_size_left".
Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a
negative number, so "*size" is assigned "buf_size_left" and goes into
the third argument of the copy_to_user function, causing a heap overflow.
This is not a security vulnerability because iwl_dbgfs_monitor_data_read()
is a debugfs operation with 0400 privileges.
