power: Add new chipset_power_on API
This is a simple API for subsystems to request the chipset to power
on. It's required so that the chargesplash state machine can request
a chipset power on upon AC connection.
Right now it's only implemented for x86 and Qualcomm as an example.
Support for other platforms can be added as required.
BUG=b:228370390
BRANCH=none
TEST=with follow-on CL, chargesplash can power on
