[RFC 3/6] drm/i915: Remove local fbdev emulation Kconfig option
Archit Taneja

Tue Mar 10 02:41:30 PDT 2015
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 #ifdefs
in certain places.
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.
