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.

+ help
+ The Denali NAND controller IP has some variations in terms of
+ the bus interface. The DMA setup sequence is completely differenct
+ between 32bit / 64bit AXI bus variants.
+
+ If your Denali NAND controller is the 64-bit variant, say Y.
+ Otherwise (32 bit), say N.

+config NAND_DENALI_SPARE_AREA_SKIP_BYTES
+ int "Number of bytes skipped in OOB area"
+ depends on NAND_DENALI
+ range 0 63
+ help
+ This option specifies the number of bytes to skip from the beginning
+ of OOB area before last ECC sector data starts. This is potentially
+ used to preserve the bad block marker in the OOB area.
