Summary0003692: Move dma_apbh descriptors to IRAM to work in suspend mode
DescriptionIf an i.MX6 board is suspended or uses low power idle, then the bus frequency is reduced and DDR3 RAM access may be impossible. If some DMA is still active at this time, then the DMA controller also can not access RAM and will fail, probably causing the board to freeze.

SDMA therefore can optionally allocate its DMA descriptors in IRAM. Add a similar option for APBH DMA driver (dma_apbh), too.
