[Why] We need to ensure that we're holding the lock on the CRTC when setting the CRC source since we're modifying the CRTC state directly. We also need to wait for any outstanding non-blocking commits to finish so they aren't reading state that's potentially being modified - non-blocking commits don't hold the CRTC lock while doing commit tail work. [How] Lock the CRTC using its mutex. While holding the lock check if there's any commit active on the CRTC - if there is, it's non-blocking and we should wait until it's finished by waiting for hw_done to be signaled since that's the last point where we touch CRTC state.
