[PATCH v2 7/9] drm/i915: Change intel_fbdev_fb_alloc() return type

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Change intel_fbdev_fb_alloc() to return struct intel_fb instead
of struct drm_framebuffer. Let's us eliminate some annoying
aliasing variables in the fbdev setup code.

v2: Assing the results to the correct variable (Jani)
    Fix xe's copy
