msm: We are using the msm2 gpu driver, not msm

Fix references that are incorrectly pointing at drivers/gpu/msm
instead of msm2.

The incorrect includes cause linaro gcc 4.8 with -O3 to produce
an unbootable kernel on the DLX.

While it doesn't seem to be affecting our normal builds, not
fixing it will likely bite us in the future in some other
mysterious way.
