g: add gpio_set_wakepin() to configure wake pins
Cr50 needs a cleaner way to enable and disable wakepins. This change
adds gpio_set_wakepin() to enable the wake pin or disable.
The gpio_set_flags() or gpio_set_flags_by_mask() remain unaffecting
wake-pin configuration.
This patch increases the flash usage by 16 bytes.
BUG=b:35587259
BRANCH=cr50
TEST=verify pinmux has the same output before and after the change on
octopus.
