dmaengine: ti: k3-udma-glue: Update name for remote RX channel device

A single RX Channel can have multiple flows. It is possible that a
single device requests multiple flows on the same RX Channel. In such
cases, the existing implementation of naming the device on the basis of
the RX Channel can result in duplicate names. The existing implementation
only uses the RX Channel source thread when naming, which implies duplicate
names when different flows are being requested on the same RX Channel.

In order to avoid duplicate names, include the RX flow as well in the name.
