Update helper function that provides gpmc-nand register
details for nand driver with bch register information.
Using this nand driver can be made self sufficient to
handle remaining gpmc-nand operations by itself instead
of relying on gpmc exported nand functions.

For common arm zImage existing nand header file
in platform specific location was moved to generic
platform data location, but it contained more than
platform data, remove it. New local header has been
created for exposing functions.
Also move gpmc-nand platform data to platform header
meant for nand from gpmc header file
