We don't really need a feature flag for has_4tile since there's a
well-defined cutover point (DG2) at which all new platforms started
using Tile4 as their Y-major tiling layout. The GT side of the code
already handles Tile4 vs legacy TileY with checks on the IP version
rather than looking at the feature flag, and we can simplify the display
code similarly (which will also make it more self-contained for re-use
in the Xe driver).
Hi Matt,
Looks good to me.

is this tab space aligned with below lines ?
Yes, it's aligned with the code below. But if you're just reading the
diff, the extra column added for the '+' at the beginning of the line
throws off the spacing.
