Driver has a bug in that it uses rflow_in_use bitmap when setting up free rflow range from TISCI but use rflow_map for reservation in __udma_reserve_rflow()
Fix this by dropping rflow_in_use bitmap array and use rflow_map for PKTDMA. BCDMA does not need rflow_in_use either.
This fixes CPSW3g not able to get DMA channels at R5 SPL on AM64x
