OCPC: Add ocpc_init()
This commit adds a ocpc_init() function which will also chain off to a
board specific init function as well. Currently, the init function
sets up the initial resistances. The board specific init functions
may set up charger specific parameters.
BUG=b:147440290
BRANCH=None
TEST=Enable on waddledee, build and flash and verify charging still
works. Verify that initial resistances are seeded.
