[PATCH i-g-t] tests/kms_plane_scaling: Require at least 30 Hz refresh rate

[Mika Kahola <mika.kahola@intel.com>]

With HDMI dummies we may end up testing a mode that doesn't really
resemble real life scenario like 4k mode with 17Hz refresh rate, which
can lead issues when executing a test. Therefore, the patch proposes
for intel-max-src-size to be tested with with real life refresh rate
such as 30 Hz or higher.
