Subject: [PATCH v2 linux-next 1/2] drivers: dma: make mux_configure32 static

There is one sparse warning in drivers/dma/fsl-edma-common.c:
drivers/dma/fsl-edma-common.c:93:6: warning: symbol 'mux_configure32'
was not declared. Should it be static?

Fix it by setting mux_configure32() as static.

Fixes: 232a7f18cf8ec ("dmaengine: fsl-edma: add i.mx7ulp edma2 version support")
