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.
