Subject: [PATCH] media: nxp: RB532: fix return value of __setup handler

imx-mipi-csis uses interfaces that are made available by VIDEO_DEV,
so the driver should depend on VIDEO_DEV to eliminate build errors.

Fixes these build errors:

aarch64-linux-ld: drivers/media/platform/nxp/imx-mipi-csis.o: in function `mipi_csis_calculate_params':
