[PATCH] drm: hisilicon: depends on MMU

[Randy Dunlap]

Prevent a kconfig warning when MMU is not enabled by making
DRM_HISI_HIBMC depend on MMU.

WARNING: unmet direct dependencies detected for DRM_TTM
  Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && MMU [=n]
  Selected by [m]:
  - DRM_TTM_HELPER [=m] && HAS_IOMEM [=y] && DRM [=m]
  - DRM_HISI_HIBMC [=m] && HAS_IOMEM [=y] && DRM [=m] && PCI [=y] && (ARM64 || COMPILE_TEST [=y])
