[PATCH] drm/msm: Fix link error with !MSM_IOMMU

The DRM driver for MSM depends on symbols from the MSM
IOMMU driver. Add this dependency to the Kconfig file.

  Kernel: arch/arm/boot/zImage is ready
  ERROR: "msm_iommu_get_ctx" [drivers/gpu/drm/msm/msm.ko]
  undefined!
  make[2]: *** [__modpost] Error 1
