chromeos: vboot and chromeos dependency removal for sw write protect state

This removes the dependency on chromeos and vboot for the sw write protect state
function: vboot_get_sw_write_protect, renamed to get_sw_write_protect_state to
both reflect this change and become consistent with the definition of
get_write_protect_state that is already in use.
