drm/amd/display: add color space option when sending link test pattern
[why]
In the TEST_MSIC dpcd register field definition, the test equipment
has the option to choose between YCbCr601 or YCbCr709.
We will apply corresponding YCbCr coefficient based on this test
request.
[how]
Add a new input parameter in dc_link_dp_set_test_pattern to allow the
selection between different color space.
