drm/ast: Convert AST driver to VRAM MM

Browse Source 
The data structure |struct drm_vram_mm| and its helpers replace ast's
TTM-based memory manager. It's the same implementation; except for the
type names.

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 ast_mmap() with drm_vram_mm_mmap()
