dt-bindings: dma: convert atmel-dma.txt to YAML

Add a description, required properties, appropriate compatibles and
missing properties like clocks and clock-names which are not defined in
the text binding for all the SoCs that are supported by microchip.
Update the text binding name `atmel-dma.txt` to
`atmel,at91sam9g45-dma.yaml` for the files which reference to
`atmel-dma.txt`. Drop Tudor name from maintainers.
