As mentioned elsewhere in this thread: We should not select user visible
options, so this patch is the only thing we can do atm (apart from
'fixing the tools' as David mentioned, but this is out of scope for an
-rc kernel)

Additionally the imx_v6_v7_defconfig should be adjusted so that the gpmi
nand driver actually gets built.
