[igt-dev] [PATCH i-g-t v2] tests/kms_rotation_crc: Remove hardcoding of platforms in igt_require()

[Radhakrishna Sripada <radhakrishna.sripada@intel.com>]

From: Anusha Srivatsa <anusha.srivatsa@intel.com>

Rework the rotate and reflect subtests by checking the
crtc supported properties against the ones that the
test is testing. Remove the hardcoded platform names in
igt_require()

v2: Make use of the property enums to get the supported rotations
