[Intel-gfx] Updated testing

[Daniel Vetter]

Hi all,

Despite the longer cycle of four weeks, not much going on ... Highlights:
- Broadcast RBG improvements and reduced color range fixes from Ville
- Ben is on a "kill legacy gtt code for good" spree, first pile of patches
  included.
- no relocs and lut improvements for faster execbuf from Chris.
- some refactorings from Imre

Happy testing!

Cheers, Daniel
