This provides a uniform interface to enable/disable legacy fbdev support for modesetting drivers, based on the discussion here:
http://lists.freedesktop.org/archives/dri-devel/2015-March/078729.html
This has only been build-tested for a few devices. Mainly looking for comments for now.
The drivers that provide fbdev emulation by default won't be impacted by this. However, if we could make all drivers use DRM_FBDEV_EMULATION, it would clean up individual Kconfigs, and have a centralized place where we touch FB_* configs.
