Revert "drm/i915: Only enable the plane after setting the fb base (pre-ILK)"
This reverts commit 49183b2818de6899383bb82bc032f9344d6791ff.
Quoth Franz Melchior:
"This patch introduces a bug on my infamous "Acer Travelmate
5735Z-452G32Mnss": when KMS takes over, the frame buffer contents get
completely garbled up on screen, with colored stripes and unreadable
text (photo on request). Only when X11 is started, the screen gets
restored again. Closing and re-opening the lid partly cures the
mess, too: it makes the font readable, though horizontally stretched."
