drm/i915: Nuke ironlake_get_initial_plane_config()

Browse Source 
The only relevant difference between i9xx_get_initial_plane_config() and
ironlake_get_initial_plane_config() is the HSW/BDW TILEOFF handling.
Add that to i9xx_get_initial_plane_config() and nuke
ironlake_get_initial_plane_config().

v2: s/plane/i9xx_plane/ etc. (James)
