drm/i915: Disable compression tricks on JSL

Browse source

Bspec asks us to disable some compression trick on JSL. While the
bspec description is pretty vague it looks like this is some extra
trick for 10bpc+ CCS which presumably the ICL derived display engine
doesn't support.

Note that we aren't currently exposing 10bpc CCS scanout support,
but once that gets added this presumably becomes an issue.
