pit: snow: Fix snow, fix up pit write protect.
A recent change to support early firmware selection on ARM broke snow and was incompletely implemented on pit. This change fixes snow by applying the remaining part of the change that had been applied to pit, and also hooks up real values in the get_write_protect_state function.
