drm/radeon/hdmi: DCE3: clean ACR control
What initially seemed to be a typo in fglrx (using register 0x740c
instead of 0x74dc) appeared to be a correct behavior. DCE3 has ACR and
CRC registers swapped which explains why we needed
WREG32(HDMI0_AUDIO_CRC_CONTROL + offset, 0x1000);
This has been tested for possible regressions on DCE3 HD3470 (RV620).
