usb_charger: initialize VBUS supplier at startup
When using VBUS_DETECT_TCPC the charger code relied on the TCPC
alert to initialize the VBUS supply, but that happens too late in
board startup sequence to allow an initally plugged in USB-C power
supply to be chosen as the active charging port.
We can and should initialize the the supplier sooner as to prevent
the charge_manager_is_seeded() check from failing thus preventing
the board from choosing a charging port.
BRANCH=none
BUG=b:77458917
TEST=PS8751 on yorp will negotiate 20V over USB-C (which was prevent
by the charge_manager not being seeded)
