regulator_register never returns NULL.

Both _en_bit and _ops parameters for all DCDCs and FETs are the same, so we
can hardcode it in tps65090_REG macro.

_en_reg can be calculated by _id + 12, so we can also remove it.

Thanks Axel, for this patch.
Just today I saw Mark's mail and about to make this change.

Applied both, thanks.  In theory it may return NULL but that's not an
error code.
