drm/tests/gpu_buddy: add a new test case for buffer clearance during resume

Browse source

Add a new unit test case for buffer clearance issue during
resume.

Using a non-power-of-two mm size, allocate alternating blocks of
4KiB in an even sequence and free them as cleared. All alternate
blocks should be marked as dirty and the split blocks should be
merged back to their original size when the blocks clear reset
function is called.
