Use the regular fbdev helpers for framebuffer I/O instead of DRM's helpers. Omapdrm does not use damage handling, so DRM's fbdev helpers are mere wrappers around the fbdev code. Add CONFIG_DRM_OMAP_FBDEV_EMULATION to select the necessary Kconfig options automatically. Make fbdev emulation depend on the new config option. By using fbdev helpers directly within each DRM fbdev emulation, we can eventually remove DRM's wrapper functions entirely.
