[Intel-gfx] [RFC 0/2] Compile out integrated

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Quicky and dirty hack based on some old ideas. Thought maybe the approach might
interest the Arm port guys. But with IS_GEN_RANGE removed easy gains are not so
big so meh.. Maybe some more easy wins with IS_DISPLAY_VER but I haven't looked
into that side.

Note debug kconfig so everything is inflated. Whether or not the relative gain
would change with production kconfig I am not sure.

P.S.
I was a bit curious there were no build errors around functions no longer used
so either there were none (would mean patch is not really that effective), or
something changed with compiler warnings/smarts. Haven't looked into it.
