[PATCH linux-next] drivers: dma: Fix sparse warning for mux_configure32

[Mao Wenan]

There is one sparse warning in drivers/dma/fsl-edma-common.c,
fix it by setting mux_configure32() as static.

make allmodconfig ARCH=mips CROSS_COMPILE=mips-linux-gnu-
make C=2 drivers/dma/fsl-edma-common.o ARCH=mips CROSS_COMPILE=mips-linux-gnu-
drivers/dma/fsl-edma-common.c:93:6: warning: symbol 'mux_configure32' was not declared. Should it be static?

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