drm/ast: Replace mapping code with drm_gem_vram_{kmap/kunmap}()

Browse source

The AST driver establishes several memory mappings for frame buffers
and cursors. This patch converts the driver to use the equivalent
drm_gem_vram_kmap() functions. It removes the dependencies on TTM
and cleans up the code.
