The patch allows to configure sensors with a remote diode connected
and a on-chip local temperature sensor from the devicetree for the
board that uses this HWM. According to the documentation [1], this is
done by setting the corresponding bits in the Mode Selection Register
(22h). It is necessary for some Intel processors (Apollo Lake SoC)
that do not support PECI and the CPU temperature is taken from the
thermistor.
TEST = After loading the nct7802 module on the Kontron mAL-10 [2] with
Linux OS, we can see configuration of the HWM with one sensor in
the thermistor mode:

This change drops maxsleep parameter from chip config and instead
hardcodes the deepest sleep state from which the WiFi device can wake
the system up from to SLP_TYP_S3. This is similar to how other device
drivers in coreboot report _PRW property in ACPI. It relieves the
users from adding another register attribute to devicetree since all
mainboards configure the same value. If this changes in the future, it
should be easy to bring the maxsleep config parameter back.

HPD on this bridge chip is a bit useless. This is an eDP bridge so the HPD is
an internal signal that's only there to signal that the panel is done powering up.
But the bridge chip debounces this signal by between 100 ms and 400 ms (depending on process,
voltage, and temperate). One particular panel asserted HPD 84 ms after it was powered on
meaning that we saw HPD 284 ms after power on. Assume that the panel driver will have the
hardcoded delay in its prepare and always disable HPD.
