[Intel-gfx] [RFC PATH i-g-t 00/15] tests/core_hotunplug: Fixes and enhancements

[Janusz Krzysztofik]

Since the test is still blocklisted due to driver issues and won't be
executed on CI, I'm providing a link where results obtained from a 
rybot run with the test removed from the blocklist can be found:
https://patchwork.freedesktop.org/series/79662/
Failures reported there come from driver and not test issues, I
believe.

Thanks,
Janusz
