drm/omap: add CONFIG_MMU dependency

Compile-testing with CONFIG_MMU disabled causes a link error in omapdrm:

arm-linux-gnueabi-ld: drivers/gpu/drm/omapdrm/omap_gem.o: in function `omap_gem_fault_2d':
omap_gem.c:(.text+0x36e): undefined reference to `vmf_insert_mixed'
arm-linux-gnueabi-ld: drivers/gpu/drm/omapdrm/omap_gem.o: in function `omap_gem_fault':
omap_gem.c:(.text+0x74a): undefined reference to `vmf_insert_mixed'

Avoid this by adding a Kconfig dependency.
