[igt-dev] [PATCH i-g-t v3 1/4] tests/kms_panel_fitting: Test cleanups.

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

Use igt_display_reset() to reset the state, instead of doing it at the
end of each subtest. Also remove the usage of a file, and instead allocate
a test pattern like the other tests do.
We now also have a way to find out if panel fitting property is supported
without performing a kmstest call.
