dmaengine: fsl-edma: fix eDMAv4 channel allocation issue

The eDMAv4 channel mux has a limitation where certain requests must use
even channels, while others must use odd numbers.

Add two flags (ARGS_EVEN_CH and ARGS_ODD_CH) to reflect this limitation.
The device tree source (dts) files need to be updated accordingly.

This issue was identified by the following commit:
commit a725990557e7 ("arm64: dts: imx93: Fix the dmas entries order")

Reverting channel orders triggered this problem.
