[Intel-gfx] [PATCH v3 02/12] drm/armada: Use regular fbdev I/O helpers

[Thomas Zimmermann]

Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Armada 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.

v2:
	* use FB_IO_HELPERS option
