drm/radeon: remove UMS support 

It's been deprecated behind a kconfig option for almost
two years and hasn't really been supported for years before
that.  DDX support was dropped more than three years ago.

Choose this option if you still need userspace modesetting.
Userspace modesetting is deprecated for quite some time now, so
enable this only if you have ancient versions of the DDX drivers.
