This patch is just the first patch  for mx6q. My following patches will
add DT to the gpmi nand driver for mx6q. Due to the dependency issue, I 
will send the patches
in the following order:
[1] mtd/gpmi: add gpmi support for mx6q.
[2] [PATCH v5] patch set about the MXS-DMA
[3] add DT support to gpmi for mx6q.

I tested this patch based on our bsp code.
