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.
