drm/hisilicon: Convert hibmc-drm driver to VRAM MM
The data structure |struct drm_vram_mm| and its helpers replace hibmc's
TTM-based memory manager. It's the same implementation; except for the
type names.
v5:
* set .llseek via DRM_VRAM_MM_FILE_OPERATIONS
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement hibmc_mmap() with drm_vram_mm_mmap()
