IMHO it is easier for me to check directly the mask, as relying to a
macro. But this is only my personal opinion.

On the other side, the GENMASK macro is taken from the kernel and it is
used by several SOCs, in U-Boot too. Maybe we like to see directly the
mask, but several users like use it and I should accept it. Both
solutions (fixing GENMASK or revert it) are fine with me.

Today a new patch was sent :

	http://patchwork.ozlabs.org/patch/556361/

same issue, fixing the GENMASK().

Troy's patch was assigned to me, but it belongs to SPI's custodian, so I
move it to Jagan.
