[igt-dev] [PATCH i-g-t] i915/gem_ccs: Use extended block-copy on MTL

[Zbigniew Kempczyński]

Integrated platforms and DG1 (exception in discrete, doesn't have
flatccs) use shorter version of block-copy blit (12 dwords length,
extended command use 22 dwords). MTL is first integrated which uses
extended block-copy instruction.

At the moment change enables using block-copy for uncompressed blits
on MTL only due to fact aux-ccs support for blitter is still unclear
for me. We haven't before code which uses aux-ccs for blitter so
enablement of this might occur in future changes.
