Presently there are no peripherals in mainline turning on writeprotect,
initially intention was to just disable writeprotect at the end of probe
and not provide platforms opportunity to enable writeprotect as none
need it, still a provision has been provided for platform to enable it.

Probably these to be taken care when there is a requirement.
