commit cdd10409914184c7eee5ae3e11beb890c9c16c61 upstream.

The "dmas" cells for the designware DMA controller need to have only 3
properties apart from the phandle: request line, src master and
destination master. But the commit 6e8887f60f60 updated it incorrectly
while moving from platform code to DT. Fix it.
