drm/fbdev-generic: Implement dedicated fbdev I/O helpers
Implement dedicated fbdev helpers for framebuffer I/O instead
of using DRM's helpers. Use an fbdev generator macro for
deferred I/O to create the callbacks. Fbdev-generic was the
only caller of the DRM helpers, so remove them from the helper
module.
v4:
* generate deferred-I/O helpers
* use initializer macros for fb_ops
v2:
* use FB_SYS_HELPERS_DEFERRED option
