[PATCH v5 04/13] drm/exynos: Use regular fbdev I/O helpers

Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Exynos does not use damage handling, so DRM's fbdev helpers
are mere wrappers around the fbdev code.
By using fbdev helpers directly within each DRM fbdev emulation,
we can eventually remove DRM's wrapper functions entirely.
v4:
* use initializer macros for struct fb_ops
v3:
* don't reorder Makefile rules (Sam)
v2:
* use FB_IO_HELPERS option
