[igt-dev] [PATCH v3 i-g-t] i915_pm_freq_api: Add some debug to tests

[Vinay Belgaumkar]

Some subtests seem to be failing in CI, use igt_assert_eq where we
compare the requested freq, which will print the values being compared.
Also print the RP values at the beginning of the test.

v2: Print GT as well (Ashutosh)
v3: Minor commit message correction (Ashutosh)
