drm/radeon/kms: add a new gem_wait ioctl with read/write flags

Browse Source 
The new DRM_RADEON_GEM_WAIT ioctl combines GEM_WAIT_IDLE and GEM_BUSY (there
is a NO_WAIT flag to get the latter) with USAGE_READ and USAGE_WRITE flags
to take advantage of the new ttm_bo_wait changes.

Also bump the DRM version.
