drm/i915: 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 fbdev callbacks. i915 was the only
caller of the DRM helpers, so remove them from the helper module.
i915's fbdev emulation is still incomplete as it doesn't implement
deferred I/O and damage handling for mmaped pages.
v4:
* generate deferred-I/O helpers
* use initializer macros for fb_ops
v2:
* use FB_IO_HELPERS options
