Cástor Muñoz 67b4e7f958 iPod Classic: use new PL080 DMA driver
This patch uses the new pl080 DMA driver for I2S playback and LCD
update. I have tried to be as fiel as possible to the current
behaviour, algorithms and configurations are the same, but using
the new driver. Other modifications:

Playback:

 - CHUNK_SIZE is decreased from 42988 to 8188 bytes, it does not
   affect normal playback (block size 1024), was tested using
   metronome (block size 46080). This change is needed because the
   new code commits d-cache range instead of commiting the whole
   d-cache, maximum time spent commiting the range should be
   limited, CHUNK_SIZE can be decreased even more if necessary.

 - pcm_play_dma_start() calls pcm_play_dma_stop() to stop the
   channel when it is running (metronome replays the tick sound
   without stopping the channel).

 - pcm_play_dma_get_peak_buffer(): same as actual SVN function but
   returns samples count instead of bytes count.
   TODO: AFAIK, actually this function is not used in RB. Not tested,
   but probably this function will fail because it returns pointers
   to the internal double buffer.

LCD update:

 - suppresses lcd_wakeup semaphore and uses yield()
