drm/ofdrm: Depend on CONFIG_MMU

Browse source 
Add a dependency on CONFIG_MMU to ofdrm. The driver uses GEM SHMEM
helpers, which require MMU support. A reported error message [1] is
shown below.

   arm-linux-gnueabi-ld: drivers/gpu/drm/drm_gem_shmem_helper.o: in function `drm_gem_shmem_fault':
   >> drivers/gpu/drm/drm_gem_shmem_helper.c:562: undefined reference to `vmf_insert_pfn'
