DRM_I915_FBDEV config is currently used to enable/disable fbdev emulation
for the i915 kms driver.
Replace this with the top level DRM_FBDEV_EMULATION config option. Using
this config lets us also prevent wrapping around drm_fb_helper_* calls with
The #ifdef in drm_i915_private struct adding/removing members intel_fbdev
and fbdev_suspend_work has been removed. This helps us use stub drm helper
functions at not much cost.
