The NAVSS UDMA will stuck if target IP module is disabled by PM while PSI-L

Hence, to avoid such situation do PSI-L threads pairing only when UDMA
channel is going to be enabled as at this time DMA consumer module expected
to be active already.
Is this patch on top of the AM64 (BCDMA/PKTDMA) series or not?
Will it cause any conflict?
No. It was not based on top of AM64 series and I've not checked for conflicts.
