[igt-dev] [PATCH i-g-t 3/4] i915_pm_freq_api: Add some basic SLPC igt tests

[Vinay Belgaumkar]

Validate basic api for GT freq control. Also test
interaction with GT reset. We skip rps tests with
SLPC enabled, this will re-introduce some coverage.
SLPC selftests are already covering some other workload
related scenarios.

v2: Rename test (Rodrigo)
v3: Review comments (Ashutosh)
v4: Skip when SLPC is disabled. Check for enable_guc is
not sufficient as kernel config may have it but the
platform doesn't actually support it.
v5: Use the updated SLPC helper
