[igt-dev] [PATCH] tests/kms_psr2_sf: Skip tests if selected fetch is not available

[Vidya Srinivas]

Currently the tests are failing on systems where selected
fetch feature is not availble. Kernel returns -EINVAL when
the test executes reporting "Invalid debug mask 4".
Patch skips if selected fetch feature is not available
in the kernel.
