[PATCH i-g-t v2 05/18] lib/rendercopy: Skip AUX surface setup in TGL+

[Juha-Pekka Heikkila]

Took a while to realize why this didn't break anything but since hw 
agree it's all ok. I wonder if on the changed line this check
"buf->ccs[0].stride" is really needed, I think that happen only with 
flatccs which doesn't exist on <gen12

Anyway,
