Imre Deak 450174fe9c drm/i915/chv: Tune L3 SQC credits based on actual latencies
While browsing BSpec I bumped into a note saying we need to tune these
values based on actual measurements done after initial enabling. I've
checked that it indeed improves things on BXT. I haven't checked this on
CHV, but here it is if someone wants to give it a go.

v2:
- Add note about the discrepancy wrt. to the spec in the formula
  calculating the credit encodings. (Mika, Ville)
- Move the WA comment to the new function. (Ville)
v3:
- Keep the comment about the SQC WA in the caller. (Ville)
