Enable driver for the emulated Imager.

config VIDEO_EMUL_IMAGER_FRAMEBUFFER_SIZE
int "Internal framebuffer size used for link emulation purpose"
default 4096
help
Configure the size of the internal framebuffer the emulated Imager
driver uses to simulate MIPI transfers. This is the first field of
dev->data, and the emulated video MIPI driver will `memcpy()` it
into the video buffer.
