extcon: intel-cht-wc: Add support for registering a power_supply class-device
The bq25890 used on the Yogabook YB1-X90 / -X91 models relies on
the extcon-driver's BC-1.2 charger detection, and the bq25890 driver
expect this info to be available through a parent power_supply
class-device which models the detected charger (idem to how the Type-C
TCPM code registers a power_supply classdev for the connected charger).
Add support for registering the power_supply class-device expected
by this setup.
