From: John Harrison <john.c.harri...@intel.com>
The gem_exec_fair test is specifically testing scheduler algorithm
performance. However, GuC does not implement the same algorithm as
execlist mode and this test is not applicable. So, until sw arch
approves a new algorithm and it is implemented in GuC, stop running
the test.
v2: Add exceptions for TGL/RKL/ADL-S - review feedback from Tvrtko.
