dma: ti: k3-udma: Query DMA channels allocated from Resource Manager

On K3 SoCs, DMA channels are shared across multiple entities, therefore
U-Boot DMA driver needs to query resource range from centralised
resource management controller i.e SystemFirmware and use DMA channels
allocated for A72 host. Add support for the same.
