Previously, the AP could only set the current wireless power state.
It couldn't determine what the EC would do in S3, nor could it get the
current wireless power state. Extend the wireless command to do so,
and add an EC console command to aid in debugging.

BRANCH=rambi
TEST=manual; expected numbers are from EC 'wireless' command
AP off -> 0x0, 0x9
AP on -> 0xd 0x9
AP suspended -> 0x9 0x9
AP on -> 0xd 0x9
ectool wireless 0x1 -> 0x1 0x9
ectool wireless 0xd -> 0xd 0x9
ectool wireless 0 0 0 0 -> 0xd 0x9 (and prints 0xd 0x9 to root shell)
ectool wireless 5 -1 -1 0 -> 0x5 0x9
AP suspended -> 0x1 0x9 (doesn't turn on 0x8, just turns off 0x4)
AP on -> 0xd 0x9
ectool wireless 0 0 0 -1 -> 0xd 0x0
AP suspended -> 0x0 0x0
AP on -> 0xd 0x9

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).

TEST=build all platforms; see that link wifi turns on at boot and off at
shutdown (verify via 'gpioget' from EC console)
