[igt-dev] [PATCH i-g-t] tests/i915/kms_frontbuffer_tracking: Skip fbcpsr testcases as needed

[Jouni Högander]

Driver is not using fbc for display versions 12 and 13 if PSR is
enabled. This is currently causing failures on fbcpsr_* subtests.

Fix this by checking display version and skipping fbcpsc_* subtests as
needed.
