davinci: dm365 evm: use EDMAQ_3 as the audio DMA queue 

By default the audio driver uses EDMAQ_0 as the DMA queue,
but on DM365 this queue is specially designed for video
transfers with a large fifo size. Having both audio and
video transfers on the same queue leads to noise on the
audio side.

This patch changes the audio queue number for DM365 to
EDMAQ_3.
