[PATCH v9 0/2] tests/kms_vrr: Add full-range refresh rate testing

[Lee Shawn C <shawn.c.lee@intel.com>]

This series extends kms_vrr to validate hardware stability across the
entire VRR refresh rate spectrum, rather than only fixed step increments.

The first patch reverts a previous workaround that started virtual RR
tests above the midpoint to avoid mode fallback. This workaround is no
longer needed once full-range testing is in place.

The second patch introduces a 'full-range' testing mode to kms_vrr.
When enabled, the test iterates from maximum down to minimum refresh
rate (stepping by 1Hz), covering all supported rates within the VRR
range. For eDP displays, the test is skipped if the panel does not
support multiple refresh rates. Standard behavior (min-to-max with
defined step size) is preserved for existing subtests.
