[igt-dev] [PATCH i-g-t v4] tests/kms_rotation_crc: Move platform checks to one place for non exhaust fence cases

[Radhakrishna Sripada]

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

Cleanup the testcases by moving the platform checks to a single function.

The earlier version of the path is posted here [1]

v2: Make use of the property enums to get the supported rotations
v3: Move hardcodings to a single function(Ville)
v4: Include the cherryview exception for reflect subtest(Maarten)
