Merge branch 'Capcom-Music-Loop'

Browse Source 
* Capcom-Music-Loop:
  Removed the fake DMA wait time as it is no longer needed after the aram-dma-fixes branch is merged.  This fixes the Resident Evil 2/3 cutscene audio in DSP LLE mode.  Fixes issue 2723.
  Changed the loop end address detection to an exact match with the current address for ADPCM audio.  Fixes the non-looping music in PN03.
