Siddharth Vadapalli 4d733efd58 dmaengine: ti: k3-udma: Enable second resource range for BCDMA and PKTDMA 
commit 566beb347e upstream.

The SoC DMA resources for UDMA, BCDMA and PKTDMA can be described via a
combination of up to two resource ranges. The first resource range handles
the default partitioning wherein all resources belonging to that range are
allocated to a single entity and form a continuous range. For use-cases
where the resources are shared across multiple entities and require to be
described via discontinuous ranges, a second resource range is required.

Currently, udma_setup_resources() supports handling resources that belong
to the second range. Extend bcdma_setup_resources() and
pktdma_setup_resources() to support the same.
