Pull hmon updates from Guenter Roeck:
 "New drivers:
   - ISL28022 power monitor
   - Nuvoton NCT7363Y

  Added support for new chips to existing drivers:
   - The tmp180 driver now supports NXP p3t1085, including its I3C mode
   - The ina2xx driver now supports SY24655 and INA260
   - The amc6821 driver now supports tsd,mule

  Other notable improvements:
   - The sht4x driver now supports the chip heater
   - The pmbus/isl68137 driver now supports a voltage divider on Vout
   - The cros_ec driver registers with the thermal framework
   - The pmbus/ltc2978 driver now supports LTC7841
   - The PMBus core now allow drivers to override WRITE_PROTECT

  Various other minor improvements and cleanups"
