[PATCH 2/2] tests/kms_psr_sink_crc: Fix edp_psr debugfs interface run only on HAS_PSR.

[Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx>]

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.
