a5xx: Define MIN_LAYERSZ and TILE_ALL like on a6xx.

TILE_ALL I looked at blits done to 2D RGB9_E5 (no UBWC) vs RGBA8
(UBWC) on pixel 2, which had the same TILE_ALL flag set and tiling on
the blits as we have seen on a6xx.  MIN_LAYERSZ I haven't verified too
closely, but setting it the same way as on a6xx fixes one of the tests
we're doing in the CTS.
