dma: ti: k3-udma: Mark flow id as valid parameter for RX channel config

Browse source 
When flow id is not marked as valid, sysfw reads the register value to
get the range of flow ids that are supported. Then compares the flow range
with the U-Boot's host id. This will definitely fail as board
configuration doesn't assign the full range to U-Boot's host id. In order
to work around this, mark the flow id as valid and pass range as 0.
