drm/vkms: init plane using drmm_universal_plane_alloc
By using drmm_universal_plane_alloc instead of
drm_universal_plane_init, we let the DRM infrastructure handles
resource allocation and cleanup. We can also get rid of some
code repetitions for plane cleanup, improving code maintainability
in vkms.
