hwmon: (max77705) Add initial support 



Maxim MAX77705 is a Companion Power Management and Type-C interface IC.
It includes charger and fuel gauge blocks, and is capable of measuring
charger input current, system bus volatage and current, and bypass
voltage.

Add support for mentioned measurements.
