mtd: denali: add Denali controller configs to Kconfig
Commit 3eb3e72a3f66 (nand/denali: Adding Denali NAND driver support) introduced some new options, and some of them were documented by commit f9860cf081ef (nand/denali: Document CONFIG symbols). This commit allows users to enable/disable them via Kconfig with more detailed help docs.

CONFIG_NAND_OMAP_GPMC
Enables omap_gpmc.c driver for OMAPx and AMxxxx platforms.
GPMC controller is used for parallel NAND flash devices, and can
