drm/i915: Do both mt and gen6 style forcewake reset on ivb probe
commit 05a2fb15 ("drm/i915: Consolidate forcewake code") failed to take into account that we have used to reset both the gen6 style and the multithreaded style forcewake registers. This is due to fact that ivb can use either, depending on how the bios has set up the machine. Mimic the old semantics before we have determined the correct variety and reset both before the ecobus probe.
