modesetting: add tile property support
This adds tiling support to the driver, it retrieves the tile info from the kernel and translates it into the server format and exposes the property. (Ported from xserver commits 8fb8bbb3062f1a06621ab7030a9e89d5e8367b35 and 6abdb54a11dac4e8854ff94ecdcb90a14321ab31) (Ported from amdgpu commit 6ee857726166f495abcd68e4ff60e3a09593d079) Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
