NFC: Fix for wrong chip version.

Whenever an ioctl call is made to check the nfcc_version we now
wake-up the nfcc. Apparently the revision ID register (metal
revision no.) is updated only when the controller comes out of
sleep. Some recent changes in the DT meant that sometimes
the incorrect chip ID was being returned and so the patch was not
being applied.This is intended to fix this problem and removes
this detail from the caller method in the DT.
