Subject: [PATCH 5.7 080/244] dmaengine: ti: k3-udma: Use correct node to read "ti,udma-atype"

From: Peter Ujfalusi <peter.ujfalusi@...com>

[ Upstream commit 9f2f3ce3daed229eecf647acac44defbdee1f7c0 ]

The "ti,udma-atype" property is expected in the UDMA node and not in the
parent navss node.

Fixes: 0ebcf1a274c5 ("dmaengine: ti: k3-udma: Implement support for atype (for virtualization)")
