Add support for manipulating the internal heater of sht4x devices.
Enabling the heater removes condensed water from the sensor surface
which disturbs the relative humidity measurements.
The heater can operate at three heating levels (20, 110 or 200
milliwatts). Also, two heating durations may be selected (0.1 or 1s).
Once the heating time elapses the heater is automatically switched off.
Changes since v3:
* struct sht4x_data: add heating_complete timestamp
* struct sht4x_data: add data_pending flag
* heater_enable_store: return -EINVAL if input != 1
* heater_enable_store: check for data->heating_complete and update it
* heater_enable_store: set data_pending flag after heating request
* sht4x_read_values: msleep if heating in progress
* sht4x_read_values: dont send measurement request if data_pending
* heater_enable attr: make it RW
* Documentation: update info about heater_enable attr

INA260 is similar to other chips of the series, except it has an internal
shunt resistor. The calibration register is therefore not present. Also,
the current register address was changed, though that does not matter for
the driver since the shunt voltage register (which is now the current
register) value is already used to read the current.

While the chips supported by this driver do not directly support current
limits, they do support setting shunt voltage limits. The shunt voltage
divided by the shunt resistor value is the current. On top of that,
calibration values are set such that in the shunt voltage register and
the current register report the same values. That means we can report and
configure current limits based on shunt voltage limits, and we can do so
with much better accuracy than by setting shunt voltage limits.

This driver exposes hardware sensors of the ASUS ROG RYUJIN II 360
all-in-one CPU liquid cooler, which communicates through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] by
Florian Freudiger.
Available sensors are pump, internal and external
(controller) fan speed in RPM, their duties in PWM, as well as
coolant temperature.
Attaching external fans to the controller is optional and allows them
to be controlled from the device. If not connected, the fan-related
sensors will report zeroes. The controller is a separate hardware unit
that comes bundled with the AIO and connects to it to allow fan control.
The addressable LCD screen is not supported in this
driver and should be controlled through userspace tools.

This driver enables hardware monitoring support for NZXT Kraken
X53/X63/X73 and Z53/Z63/Z73 all-in-one CPU liquid coolers.
All models expose liquid temperature and pump speed (in RPM), as well as
PWM control (natively only through a temp-PWM curve, but the driver also
emulates fixed PWM control on top of that). The Z-series models
additionally expose the speed and duty of an optionally connected fan,
with the same PWM control capabilities.
Pump and fan duty control mode can be set through pwm[1-2]_enable,
where 1 is for the manual control mode and 2 is for the liquid temp
to PWM curve mode. Writing a 0 disables control of the channel through
the driver after setting its duty to 100%. As it is not possible to query
the device for the active mode, the driver keeps track of it.
The temperature of the curves relates to the fixed [20-59] C range, per
device limitations, and correlating to the detected liquid temperature.
Only PWM values (ranging from 0-255) can be set.
The addressable RGB LEDs and LCD screen, included only on Z-series models,
are not supported in this driver.
