Shawn Guo 62477adf5f ASoC: mxs: move to use generic DMA helper
With mxs-dma converted to generic DMA bindings, let's move mxs-pcm to
use it by removing flages SND_DMAENGINE_PCM_FLAG_NO_DT and
SND_DMAENGINE_PCM_FLAG_COMPAT.  As the result, those mxs custom dma
params code can be removed now.

* Freescale MXS Serial Audio Interface (SAIF)
Required properties:
- compatible: Should be "fsl,<chip>-saif"
- reg: Should contain registers location and length
- interrupts: Should contain ERROR interrupt number
- dmas: DMA specifier, consisting of a phandle to DMA controller node
and SAIF DMA channel ID.
Refer to dma.txt and fsl-mxs-dma.txt for details.
- dma-names: Must be "rx-tx".
Optional properties:
- fsl,saif-master: phandle to the master SAIF. It's only required for
the slave SAIF.
Note: Each SAIF controller should have an alias correctly numbered
in "aliases" node.
Example:
aliases {
saif0 = &saif0;
saif1 = &saif1;
};
saif0: saif@80042000 {
compatible = "fsl,imx28-saif";
reg = <0x80042000 2000>;
interrupts = <59>;
dmas = <&dma_apbx 4>;
dma-names = "rx-tx";
};
saif1: saif@80046000 {
compatible = "fsl,imx28-saif";
reg = <0x80046000 2000>;
interrupts = <58>;
dmas = <&dma_apbx 5>;
dma-names = "rx-tx";
fsl,saif-master = <&saif0>;
};
