MLK-19888 gpu: imx: dpu: common: Use stream1 as the master stream for i.MX8QM
Pixel combiner uses two display streams to drive one single display.
Either one of the two streams can be master stream and the other
slave stream. If we use stream0 as the master stream, the overlay
covers the two streams could be unsynchronized sometimes. It looks
like there is one frame lag between the two streams. However, it
turns out that using stream1 as the master stream can workaround
this issue.
