[PATCH libdrm] radeon: Fix 1D tiling layout on SI.

From: Michel D?nzer Very similar to Evergreen, but slightly different rules for tile / slice alignment. Fortunately, these map quite naturally onto the previous fixes for linear aligned layout on SI. 2D tiling still needs more work here and possibly in the kernel. Signed-off-by: Michel D?nzer
