[PATCH 13/14] ARM: OMAP2+: Convert NAND to retrieve GPMC settings from DT

When booting with device-tree, retrieve GPMC settings for NAND from
the device-tree blob. This will allow us to remove all static settings
stored in the gpmc-nand.c in the future once the migration to
device-tree is complete.
