[Intel-gfx] [PATCH 04/12] tests/kms_psr_sink_crc: Fix edp_psr debugfs interface

[Rodrigo Vivi]

Tests were broken on platforms that doesn't have psr or on new kernel that contains new interface.
A lot more need to be done to get these tests really useful, but for now lets avoid it breaking
tests framework.

v2: Doesn't duplicate kernel's HAS_PSR. skip based on debugfs output.
