drm/amd/display: Add KUnit test for CRC function

Browse source

DM CRC parsing functions are an easy candidate for exploring the use of
KUnit unit-testing frameworks. Add a few tests for the same.

The test file and .kunitconfig are placed under amdgpu_dm/tests/ to
follow the convention of keeping test code separate from production
sources.
