chromeos: clean up "recovery" and "write protect" GPIOs
The "write protect" GPIO's cached value is never actually
read after entering depthcharge. Ensure the value from
get_write_protect_state() is being transferred accurately,
so that we may read this GPIO value in depthcharge without
resampling.
The cached value of the "recovery" GPIO is read only on certain
boards which have a physical recovery switch. Correct some of
the values sent to boards which presumably never read the
previously incorrect value. Most of these inaccuracies are from
non-inverted values on ACTIVE_LOW GPIOs.
