tcpc: Add common routine to check power
This comment is from CL:1123314:
We do not want to allow depthcharge to suspend the PD port for a
firmware upgrade if there is not enough battery power to last during
the full firmware upgrade.
A common routine is created to check power:
pd_firmware_upgrade_check_power_readiness() in usb_common.c.
Firmware upgrade which needs to suspend PD port should check
this function to make sure there is enough power.
BUG=none
BRANCH=none
TEST=make -j buildall
