tcpm: Parse and log AVS APDO

Browse source

The USB PD specification introduced new Adjustable Voltage Supply (AVS)
types for both Standard Power Range (SPR) and Extended Power Range (EPR)
sources.

Add definitions to correctly parse and handle the new AVS APDO. Use
bitfield macros to add inline helper functions to extract voltage,
current, power, and peak current fields to parse and log the details
of the new EPR AVS and SPR AVS APDO.
