mtd: nand: mxs: fix cache alignment for cache lines >32
Currently the command buffer gets allocated with a size of 32 bytes.
This causes warning messages on systems with cache lines bigger than
32 bytes:
CACHE: Misaligned operation at range [9df17a00, 9df17a20]
Define command buffer to be at least 32 bytes, but more if cache
line is bigger.
