ENGR00304914-1 ASoC: imx-hdmi-dma: Limit period size for 6DQ
The HDMI IP in i.MX6DQ has a bug that it limits the dma period size within 8K.
Patch 'ENGR00300188-1 ASoC: imx-hdmi-dma: Double the buffer and period sizes'
doubled the period size which works great with Dual Lite but broke the HDMI
audio function on DQ. Thus fix it for 6DQ case.
