mtd: denali: add Denali controller configs to Kconfig 

Commit 3eb3e72a3f (nand/denali: Adding Denali NAND driver support)
introduced some new options, and some of them were documented by
commit f9860cf081 (nand/denali: Document CONFIG symbols).

This commit allows users to enable/disable them via Kconfig
with more detailed help docs.

help
Enable support for the Denali NAND controller.

bool "Use 64-bit variant of Denali NAND controller"
depends on NAND_DENALI
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.

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.
