sunxi: nand: Add board configuration options
When SPL_NAND_SUNXI option is selected in config, set some configuration
options for sunxi NAND.
This commit also introduces the configurable options in Kconfig.

This is a small implementation of the Denali NAND controller
for use on SPL.
+config SPL_NAND_SUNXI
+ bool "Support for NAND on Allwinner A20 in SPL"

+ Enable support for NAND. This option allows SPL to read from
+ sunxi NAND using DMA transfers.
+ Depending on the NAND chip, values like ECC strength and page sizes
+ have to be configured.

+ End address for boot partitions on NAND. Those partitions have a

+config NAND_SUNXI_SPL_ECC_STRENGTH
+ int "ECC Strength for sunxi NAND"
+ default 40
+ depends on SPL_NAND_SUNXI
+ ---help---
+ ECC strength used by the sunxi NAND SPL driver. This is specific to the
