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.
