[Intel-gfx] [PATCH igt 2/2] tests/gem_exec_suspend: Add basic s4-devices subtest

[Imre Deak]

Add a new subtest that performs suspend-to-disk, but instead of doing
the full sequence it suspends/resumes only devices. A failed s4 subtest
and a successful s4-devices subtest would indicate a kernel core or BIOS
problem as opposed to some issue in the driver.
