drm/amd/display: Split out DC programming for CRC capture
[Why] Calling amdgpu_dm_crtc_set_crc_source in amdgpu_dm directly has the consequence of adding additional vblank references or starting DPRX CRC capture more than once without calling stop first. Vblank references for CRC capture should be managed entirely by opening and closing the CRC file from userspace. Stream state also shouldn't be required on the CRC so we can close the file after the CRTC has been disabled. [How] Do DC programming required for configuring CRC capture separately from setting the source. Whenever we re-enable or reset a CRC this programming should be reapplied. CRC vblank reference handling in amdgpu_dm can be entirely dropped after this. Stream state also no longer needs to be required since we can just defer the programming to when the stream is actually enabled.
