Add new cell for sw_done/sw_done_selector, because PDM need enable
software done feature in sdma script.
The new fourth cell defined as below:
Bit31: sw_done
Bit15~bit0: selector
For example: 0x80000000 means sw_done enabled for done0 sector which
is for PDM on i.mx8mm.

On i.mx8 mscale B0 chip, AHB/SDMA clock ratio 2:1 can't be supportted,
since SDMA clock ration has to be increased to 250Mhz, AHB can't reach
to 500Mhz, so use 1:1 instead.

cherry-pick below patch from v3.14.y:
ENGR00329948-3: dma: imx-sdma: Add hdmi audio support
in sdma
There's a missing script for hdmi audio support in current sdma driver,
thus add it.
This HDMI script doesn't use bd to copy memory like a normal one does
but only to update the memory address for HDMI internal AHB DMA and
then trigger its procedure automatically.

Shared Peripheral ASRC, running on SPBA, needs to use shp sciprts for
DMA transfer. So this patch just adds a new DMATYPE for it.

imx25 did not work without a firmware previously.
This patch adds a DT compatible to pass the correct data with the
default script addresses for imx25.
Add imx25 compatible to the list of compatibles in the binding
documentation.

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.

This adds the ROM script addresses for i.MX25, i.MX5x and i.MX6 to the
SDMA driver needed for the driver to work without additional firmware.
The ROM script addresses are SoC specific and in some cases even tapeout
specific. This patch adds the ROM script addresses only for SoCs which
do not have a tapeout specific SDMA ROM, because currently it's unclear
how this case should be handled.

Update imx-sdma driver to adopt generic DMA device tree bindings. It
calls of_dma_controller_register() with imx-sdma specific of_dma_xlate
to get the generic DMA device tree helper support. The #dma-cells for
imx-sdma must be 3, which includes request ID, peripheral type and
priority.
The existing way of requesting channel, clients directly call
dma_request_channel(), still work there, and will be removed after
all imx-sdma clients get converted to generic DMA device tree helper.
