bc12: create bc12 driver structure
To support linking multiple bc12 drivers into ec binary, we have to
remove the common symbols in drivers.
This CL creates a bc12_drv structure to hold the original driver-specific
usb_charger_* functions, and implements common usb_charger_* functions
which whill dispatch the function call based on the information in
bc12_drv table.
Also add a CONFIG_BC12_SINGLE_DRIVER and enabled by default for
backward compatibility. If CONFIG_BC12_SINGLE_DRIVER is defined,
a default bc12_drv array with proper size and content will be created
for the board.
BUG=b:155611686
TEST=1) make buildall.
2) verify single driver mode on krane (rt946x) and juniper
(pi3usb9201).
3) verify multiple driver works on asurada, see CL:2189624 for
example usage.
4) verify single driver multi chip on blooglet.
