[PATCH -next] media: stm32-dma2d: fix Kconfig dependencies grouping

[Randy Dunlap]

On x86_64, when
CONFIG_COMPILE_TEST=y
CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_V4L2=m
CONFIG_VIDEO_STM32_DMA2D=y

there are many build errors (this is only a sampling of them):

ld: drivers/media/common/videobuf2/videobuf2-core.o: in function `vb2_core_streamon':

Regrouping the depend items limits the STM32_DMA2D symbol to =m,
so that the build errors are eliminated.
