Rodrigo Siqueira 559e50fd34 drm/vkms: Add dumb operations
VKMS currently does not handle dumb data, and as a consequence, it does
not provide mechanisms for handling gem. This commit adds the necessary
support for gem object/handler and the dumb functions.

Changes since V1:
 Daniel Vetter:
 - Add dumb buffer support to the same patchset
Changes since V2:
 Haneen:
 - Add missing gem_free_object_unlocked callback to fix the warning
   "Memory manager not clean during takedown"
