[U-Boot] [PATCH] nand/spl: Assuming a static nand page size to reduce code size

[Matthew McClintock]

Change variables to const to reduce code size, these values are
hardcoded via defines anyways so we might as well assume they
are constants

With this change we can reduce the size of the nand_spl by
148 bytes with my particular board/compiler
