drm/amd/display: Implement wait_for_odm_update_pending_complete [WHY] Odm update is doubled buffered. We need to wait for ODM update to be completed before optimizing bandwidth or programming new udpates. [HOW] implement wait_for_odm_update_pending_complete function to wait for: 1. odm configuration update is no longer pending in timing generator. 2. no pending dpg pattern update for each active OPP.

drm/amd/display: Raise DPG height during timing synchronization [Why] Underflow counter increases in AGM when performing some mode switches due to timing sync, which is a known hardware issue. [How] Temporarily raise DPG height during timing sync so that underflow is not reported.

drm/amd/display: program DPG_OFFSET_SEGMENT for odm_pipe [why] When test pattern is enabled with ODM combine, test pattern is generated by piecing multiple DPGs image together. The current code will program all DPGs with horizontal offset of 0. This will cause all DPGs to output the beginning of the pattern. Instead each DPG should program a horizontal offset of its x position to form a continous pattern when pieced together.

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.
