[PATCH 12/14] arm64: dts: imx8qm: add dma ss support

[Aisheng Dong <aisheng.dong@nxp.com>]

The DMA SS of MX8QM is mostly the same as the DMA part in MX8QXP ADMA SS
while it has one more instance for each of LPUART, ADC and LPI2C. And unlike
MX8QXP that flexcan clocks are shared between multiple CAN instances,
MX8QM has separate flexcan clock slice.

So we reuse the most part of common imx8-ss-dma.dtsi and add new things
based on it.
