google/chromeec: Revise parameters of EC USB PD API call
This patch adds voltage and curent parameters in
google_chromeec_get_usb_pd_power_info and remove power parameter. Caller could
use the voltage and current information to calculate charger power rating.
The reason for this change is, some applications need the voltage information
to calculate correct system power eg PsysPmax.
