GPMC has NAND registers, update nand platform data with those details
so that NAND driver can configure those by itself instead of using
exported symbols.

This has been made for migrating boards one by one so that

Modify board_onenand_init to return platform data. This
would be required for boards to be able to pass it to
gpmc driver so that it finally reaches onenand driver.
Also un-static the function so that boards can use it.

Currently gpmc is configured in platform for nand.
As configuring gpmc has been moved to gpmc driver,
populate details needed for the driver to configure
gpmc. gpmc driver would configure based on this
information.
