drm/i915: Only enable the plane after setting the fb base (pre-ILK)
When enabling the plane, it is helpful to have already pointed that plane to valid memory or else we may incur the wrath of a PGTBL_ER. This code preserved the behaviour from the bad old days for unknown reasons... Found by assert_fb_bound_for_plane().
