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.
