Sink CRC is the most reliable way to test PSR. However in some platforms
apparently auto generated packages force panel to keep calculating CRC invalidating
our current sink crc check over debugfs.

So, this manual test help us to find possible gaps on this platforms where we cannot
trust on sink crc checks.

v2: Accept Daniel's suggestions:
    * Avoid strcpy
    * don't override assert definition
    * Make --interactive-debug for every testcases instead using local --manual

v3: Sink CRC can be unreliable for other platforms as well so let's skip and warn
    when we detect the misbehaviour instead hardcoded per platform.
