Subject: [PATCH 5.7 120/244] dmaengine: ti: k3-udma: Disable memcopy via MCU NAVSS on am654

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

commit a4e688535a0829980d5ef1516c0713777a874c62 upstream.

Trace of a test for DMA memcpy domains slipped into the glue layer commit.
The memcpy support should be disabled on the MCU UDMAP.
