Cr50: Specify pinmux wake sources in gpio.inc
This adds (and uses) some additional flags for gpio.inc's
PINMUX() macro, to configure specific pads as wake sources when
the SoC is sleeping.
BUG=chrome-os-partner:49955
BRANCH=none
TEST=make buildall; test on Cr50
The sleep/deep sleep behavior is unchanged. This just replaces
hard-coded wake sources with pads configured in gpio.inc and the
chip/g/sps.c module. Tests from previous CLs still pass.
