Additional TEMP registers for nct6798d, nct6799d-r and nct6796d-s
This allows the max/max_hyst/crit attributes to be shown/stored
* Increase NUM_TEMP from 10 to 12
* Separate TEMP/MON_TEMP/OVER/HYST/CRIT registers
* Rename "PECI Calibration" to include "TSI" too
* Update ALARM/BEEP bits for temps for 6799
* For 6799, keep temp_fixed_num at 6, but increase
num_temp_alarms/num_temp_beeps to 7/8
Tested with NCT6799D-R showing additional sysfs attributes:
* temp3-temp8: max/max_hyst/beep/alarm
* temp3-temp6: crit/offset

Add base support for Renesas HS3001 temperature
and humidity sensors and its compatibles HS3002,
HS3003 and HS3004.
The sensor has a fix I2C address 0x44. The resolution
is fixed to 14bit (ref. Missing feature).
Missing feature:
- Accessing non-volatile memory: Custom board has no
possibility to control voltage supply of sensor. Thus,
we cannot send the necessary control commands within
the first 10ms after power-on.

The following warning is given by the Smatch static checker:
drivers/hwmon/hp-wmi-sensors.c:1937 hp_wmi_sensors_init()
error: uninitialized symbol 'pevents'.
If there are no instances of the HPBIOS_PlatformEvents WMI object
available, init_platform_events() never initializes this pointer,
which may then be passed to hp_wmi_debugfs_init() uninitialized.
The impact should be limited because hp_wmi_debugfs_init() uses this
pointer only if the count of HPBIOS_PlatformEvents instances is _not_
zero, while conversely, it will be uninitialized only if the count of
such instances _is_ zero. However, passing it uninitialized still
constitutes a bug.

Add support for MP2971 and MP2973, the successor of MP2975.
The major differences are:
- On MP2973 and MP2971 the Vref cannot be read and thus most of
the OVP/current calculations won't work.
- MP2973 and MP2971 also support LINEAR format for VOUT
- MP2973 and MP2971 do not support OVP2
- On MP2973 and MP2971 most registers are in LINEAR format
- The IMVP9_EN bit has a different position
- Per phase current sense haven't been implemented.
As on MP2975 most of the FAULT_LIMIT and WARN_LIMIT registers
have been redefined and doesn't provide the functionality as
defined in PMBUS spec.
Tested on MP2973 and MP2971.

In order to upstream MP2973/MP2971 simplify the code by removing support
for various VOUT formats. The MP2973 and MP2971 supports all PMBUS
supported formats for VOUT, while the MP2975 only support DIRECT and
VID for VOUT.
In DIRECT mode all chips report the voltage in 1mV/LSB.
Configure the chip to use DIRECT format for VOUT and drop the code
conversion code for other formats. The to be added chips MP2973/MP2971
will be configured to also report VOUT in DIRECT format.
The maximum voltage that can be reported in DIRECT format is 32768mV.
This is sufficient as the maximum output voltage for VR12/VR13 is
3040 mV.

* Increase available bits, IN: 16 to 24, FAN: 8 to 12,
TEMP: 6 to 12
* Reorder alarm/beep definitions to match in order to allow
additional inputs in the future
* Remove comments about 'unused' bits as probe() is a better
reference
Testing note:
* Tested on nct6799 with IN/FAN/TEMP, and changing min/max/high/hyst,
that triggers the corresponding alarms correctly. Good confirmation
on the original mapping of the registers and masks.
As to be expected, only 4 fans and 2 temps (fixed) have limits
currently on nct6799 on my board.
* Trouble with testing intrusion alarms and beeps, no way to confirm
those. As I understand now, intrusion/caseopen is probably not
connected on my board.
And I haven't seen a buzzer on a board in ages.

SMM665 and related chips are power controller/sequencer chips from
Summit Microelectronics. The company was acquired by Qualcomm in 2012,
and support for the chip series stopped.
The chips are long since gone from active use, making the driver
unsupportable and just consuming space and compile time. Remove it.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Add a 200ms delay after sending a ctrl report to Quadro,
Octo, D5 Next and Aquaero to give them enough time to
process the request and save the data to memory. Otherwise,
under heavier userspace loads where multiple sysfs entries
are usually set in quick succession, a new ctrl report could
be requested from the device while it's still processing the
previous one and fail with -EPIPE. The delay is only applied
if two ctrl report operations are near each other in time.
Reported by a user on Github [1] and tested by both of us.
