tests/pm_rpm: add subtests for planes and cursors

Browse Source 
These tests should trigger WARNs on Kernels that don't have the most
recent fixes.

v2: - Merge both the cursor and planes patches into one so it's easier
      to update them.
    - Extend the tests a little bit to exercise fences.
    - Fix bug found by Matt to enable the test to run on older Kernels
