drm/i915: Check if BIOS enabled dual-channel LVDS on 8xx, not only on 9xx Commit 0c2e39525b3b53a97a0202c5f35058147e53977e is not sufficient to get fd.o bug #20115 fixed. In addition intel_find_best_PLL() must not only rely on BIOS settings for i9xx chips but also for i8xx, so drop the IS_I9XX() check.
