drivers: power: add pd chip driver

This temporary patch is to solve the problem that the rk3588s
tablet can be turned on when the battery is out of power.
This Type-C PD driver only supports PD fast charging function,
compatible with PD fusb302 and husb311 chip. If DFP/UFP detection
and dp altmode functions are added later, we will revert this patch.
