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().
