freedreno/a6xx: fix issues with gallium HUD

In some cases the draw for the text wasn't working.  This seems to be
fixed by resyncing some of the "golded registers" from blob (initial
values were based on somewhat older blob version).

Perhaps good to have a bit of soak time on master, but would be good
to eventually land in 19.x stable branches.
