usb_charger: move common usb charger code out of board directory
Move common USB charger code out of board directory including
setting VBUS supplier when VBUS changes, and initializing BC1.2
supplier types on init.
This also enables re-enabling of Pericom BC1.2 detection interrupts
when VBUS is changed on all boards that use USB_CHG task.
BUG=chrome-os-partner:42292
BRANCH=none
TEST=make -j buildall. Tested on glados and samus by plugging in
a few different chargers and making sure we charge.
