This patch adds a new DMA_TYPE for SSI dual FIFO script, included
in SDMA firmware version 2. This script would allow SSI use dual
fifo mode to transimit/receive data without occasional hardware
underrun/overrun.

On i.MX5/6 series, SDMA is using new version firmware to support SSI
dual FIFO feature and HDMI Audio (i.MX6Q/DL only). Thus add it.

By enabling dual fifo mode, it would allow SSI enter a better performance
to transimit/receive data without occasional hardware underrun/overrun.

When using pool space for DMA buffer, there might be duplicated calling
of gen_pool_alloc() and gen_pool_virt_to_phys() in each implementation.
Thus it's better to add a simple helper function, a compatible one to
the common dma_alloc_coherent(), to save some code.

or figure out why your System would hang with current sgtl5000 driver. If it
really has a critical bug in its regulator-related code, I think you can then
make a greater contribution by fixing the bug rather than bypassing it.
