Add 'dmas' and 'dma-names' properties to describe optional DMA support
for RX and TX channels in the LINFlexD UART controller.

Same question as in other patch about existing devices.

I will update the bindings so that `dmas`/`dma-names` are optional for S32G and not present on S32V234. Would this be acceptable?

Thanks,
Larisa

This allows the device tree to specify DMA channels used for UART data
transfers. If not specified, the driver will fall to interrupt-based
operations.
