gpio: Use callback presence to determine need of valid_mask

After we switched the two drivers that have .need_valid_mask
set to use the callback for setting up the .valid_mask,
we can just use the presence of the .init_valid_mask()
callback (or the OF reserved ranges, nota bene) to determine
whether to allocate the mask or not and we can drop the
.need_valid_mask field altogether.
