Oh dear, the basic test was completely lost when we've merged the sink_crc
debugfs support :( Applied now, thanks for the patch.
One comment below.

Just one comment here: Do we really need to check for edp here (same for
the kernel btw)? Afaik sink crc is a generic DP feature, but obligatory
for edp with psr. So would make sense to also run the basic test on other
DP ports, just to give it a bit more testing.
