tests/frontbuffer_tracking: Do not test sink crc
eDP sink crc reads use vblank interrupts that cause PSR exit and
therefore makes them unsuitable for PSR testing. Besides that, reading
sink CRC via the AUX channel for testing when the HW also is most likely
is going to be using AUX channel is a recipe for inconsistent test
results. Thirdly, CRC's have been seen to be noisy or vary across sinks for
the same driver and test code. We tradeoff the ability to validate what the
sink is displaying for correctness.
