arm64: dts: broadcom: drop useless 'dma-channels/requests' properties

The pl330 DMA controller provides number of DMA channels and requests
through its registers, so duplicating this information (with a chance of
mistakes) in DTS is pointless.  Additionally the DTS used always wrong
property names which causes DT schema check failures - the bindings
documented 'dma-channels' and 'dma-requests' properties without leading
hash sign.
