Split wireless power/radio control out of switch.c

Chipset control of wireless power uses the new API instead of overriding
the wireless power itself.

Refactor board-specific support for it to just a few config #defines
instead of board-specific functions.  This makes some assumptions
about the polarity of the enable signals.  Not making those
assumptions would require defining an array of structs or some other
heavier-weight board-specific info.  Since the assumptions hold for
all current boards, let's make them now because this is a step in the
right direction, and reserve doing something more general until we
actually have a use case for it (so we build in just the flexibility
we need).

BUG=chrome-os-partner:18343
BRANCH=none
TEST=build all platforms; see that link wifi turns on at boot and off at
     shutdown (verify via 'gpioget' from EC console)
