This adds the rx/tx DMA channels for CSPI peripherals. Channel numbers
are taken from i.MX7D RM Rev1 01/2018.
Peripheral types ID (7) is selected according to fsl,imx-sdma.yaml and
is similar to i.MX6 and i.MX8M platforms. Same goes for transfer
priority ID (last number).

Tested on TQMa7D/MBa7x using the on-board SPI attached NOR flash.

This adds the rx/tx DMA channels for CSPI peripherals. Channel numbers
are taken from i.MX7D RM Rev1 01/2018.
Peripheral types ID (7) is selected according to fsl,imx-sdma.yaml and
is similar to i.MX6 and i.MX8M platforms. Same goes for transfer
priority ID (last number).
