The current code is actually wrong. chv doesn't require X-tiling for
reflection.
I think the actual hardware restrictions we have are:
gen4+: 0/180 degree rotation supported always
chv: supports reflection, except with 180 degree rotation
gen9+: 90/270 degree rotation supported with y/yf tiling
gen10+: supports reflection, except with linear fb
