Revert "compositor-drm: disable hardware cursors"

Browse Source 
This reverts commit 6858383d51.

The main reason for the original patch was a regression on the Intel
drivers causing compositor framerate to drop to half during cursor
updates or motion. The Intel problem was fixed in
2e7f43c41c
The fix is included in Linux 4.1-rc6 and 4.0.5.

The comment in the original patch is still true, but arguably the
possible minor glitches with cursor updates are less bad than not using
cursor planes at all.
