dma: ti: k3-udma: Fix BCDMA probe by adding check for MMR_RFLOW
RFLOW config related MMR does not exist incase of BCDMA.
Add check to bypass the RFLOW MMR extraction.
Without this, the probe sequence fails checking for
the MMR_RFLOW region, which is valid only for packet based
DMA and obselete for BCDMA.
Fixes: 5abb694d6016 ("dma: ti: k3-udma: Add support for native configuration of chan/flow")
