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.
