Just everything you need for UVD with r600g and radeonsi.

v2: move UVD code to radeon subdir, clean up build system additions,
    remove an unused SI function, disable tiling on SI for now.
v3: some minor indentation fix and rebased
v4: dpb size calculation fixed
v5: implement proper fall-back in case the kernel doesn't support UVD,
    based on patches from Andreas Boll but cleaned up a bit more.
