dt-bindings: dma: fsl-edma: add dma-channel-mask property description
Add documentation for the dma-channel-mask property in the fsl-edma
binding. This property uses an inverted bit definition: bit value 0
indicates the channel is available, while bit value 1 indicates
unavailable.
That was already used widely for i.MX8, i.MX9. Correcting the definition
will break backward compatibility. This reversal only impacts the eDMA
dts node and driver, and doesn't impact DMA consumer. Therefore,
keep the inverted definition.
Also add a note at the top of the binding to highlight this inverted
definition to prevent confusion.
