The XTAL SI is a serial interface to indirectly access registers of
analog hardware circuit. Since WiFi 7 chips use different registers, add
a ops to access them via common functions. This patch doesn't change logic
for existing chips.

With formatted string loaded from firmware file, we can use the formatted
string ID and get corresponding string, and then use regular rtw89_debug()
to show the message if debug mask of RFK is enabled.
If the string ID doesn't present, fallback to print plain hexadecimal.

RFK log events contains two types. One called RUN log is to reflect state
during RFK is running, and it replies on formatted string loaded from
firmware file, but print this type as plain hexadecimal only in this patch.
The other is REPORT log that reflects the final result of a RFK, and
each calibration has its own struct to carry many specific information.

Trigger a RFK (RF calibration) in firmware by a H2C command, and in
progress it reports log and a result finally by C2H events. Firstly, add
prototype of the C2H event handlers to have a simple picture of framework.
The callers who trigger H2C will wait until a C2H event is received,
so we must process these C2H events in receiving process. Thus, mark this
kind of C2H events as atomic. Also, timestamp is also useful for
debugging, mark C2H events carrying RFK log as atomic as well.

To debug RFK (RF calibration) in firmware, it sends log via firmware C2H
events to driver with string format ID and four arguments. Load formatted
string from firmware file, and the string ID can get back its string. Then,
use regular print format to show the message.

+============================================+
* a firmware file can contains more than one elements with this element ID
named RTW89_FW_ELEMENT_ID_RFKLOG_FMT (19), because many RFK needs its
own formatted strings, so add 'rfk_id' to know it belongs to which RFK.
* the 'formatted string' just follow 'offset[]' without padding to align
32bits.

AP BSSID configuration is missing at AP start. Without this fix, FW returns
STA interface MAC address after first init. When hostapd restarts, it gets MAC
address from netdev before driver sets STA MAC to netdev again. Now MAC address
between hostapd and net interface are different causes STA cannot connect to
AP. After that MAC address of uap0 mlan0 become the same. And issue disappears
after following hostapd restart (another issue is AP/STA MAC address become the
same).
This patch fixes the issue cleanly.

When the MAC address read from the efuse data is invalid, warn the
user and use a random MAC address instead.
On a device I am currently using (Anbernic RG-ARC) with a rtw8821cs
the efuse appears to be incompletely/improperly programmed. The MAC
address reads as ff:ff:ff:ff:ff:ff. When networkmanager attempts to
initiate a connection (and I haven't hard-coded a MAC address or
set it to random) it fails to establish a connection.

Sometimes there may be reasons for which a BSS that's
actually found in scan cannot be used to connect to,
for example a nonprimary link of an NSTR mobile AP MLD
cannot be used for normal direct connections to it.
Not indicating these to userspace as we do now of course
avoids being able to connect to them, but it's better if
they're shown to userspace and it can make an appropriate
decision, without e.g. doing an additional ML probe.
Thus add an indication of what a BSS can be used for,
currently "normal" and "MLD link", including a reason
bitmap for it being not usable.
The latter can be extended later for certain BSSes if there
are other reasons they cannot be used.

There's only one user of this code, which is STA unblock
during sleep for uAPSD on really old devices. Instead of
having this all through the API with calls up and down,
just implemented a special-case CMD_BLOCK_TXQS flag for
this, it's only needed in the old gen1 transport.
While at it, fix a complain that lockdep would have, as
we lock the cmd queue and then the TXQs in the reclaim
by using spin_lock_nested(). We no longer need to disable
BHs in iwl_trans_pcie_block_txq_ptrs() since it's called

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.
Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.
