r300-gallium: Don't set GB_TILE_CONFIG (in userspace.)

This accompanies kernel patches that make GB_TILE_CONFIG's various members
completely controlled in DRM.

GB_TILE_CONFIG has the following controls:
 - The number of GB (pixel) pipes enabled
 - The size and style of tiling
 - Subpixel precision (either 1/12 or 1/16)

Per airlied and glisse, userspace and kernel will now agree (always) on
a subpixel precision of 1/12, and tiling will always be kernel-controlled.
