hw/sensor: add Maxim MAX31785 device

Browse Source 
MAX31785 is a PMBus compliant 6-Channel fan controller. It supports 6 fan
channels, 11 temperature sensors, and 6-Channel ADC to measure the remote
voltages. Datasheet can be found here:
https://datasheets.maximintegrated.com/en/ds/MAX31785.pdf

This initial version of the driver has skeleton and support for the
fan channels. Requests for temperature sensors, and ADC Channels the
