Various Kconfig options selected the per-architecture helpers for
fbdev. But none of the contained code depends on fbdev. Standardize
on CONFIG_VIDEO, which will allow to add more general helpers for
video functionality.

CONFIG_VIDEO protects each architecture's video/ directory.

Your patch in general looks good.
But is renaming the config option from CONFIG_FB_CORE to CONFIG_VIDEO
the best choice?
CONFIG_VIDEO might be mixed up with multimedia/video-streaming.

Why not e.g. CONFIG_GRAPHICS_CORE?
I'm fine with CONFIG_VIDEO as well, but if someone has a better idea
we maybe should go with that instead now?

This
allows for the use of more fine-grained control for each directory's
files, such as the use of CONFIG_STI_CORE on parisc.

v2:
- sparc: rebased onto Makefile changes
