drm/vram: Implement lazy unmapping for GEM VRAM buffers
Frequent mapping and unmapping a buffer object adds overhead for
modifying the page table and creates debug output. Unmapping a buffer
is only required when the memory manager evicts the buffer from its
current location.
v4:
* WARN_ON if buffer is still mapped during BO cleanup
