Chris Wilson e28f871165 drm/i915: Fix unfenced alignment on pre-G33 hardware
Align unfenced buffers on older hardware to the power-of-two object
size.  The docs suggest that it should be possible to align only to a
power-of-two tile height, but using the already computed fence size is
easier and always correct. We also have to make sure that we unbind
misaligned buffers upon tiling changes.

In order to prevent a repetition of this bug, we change the interface
to the alignment computation routines to force the caller to provide
the requested alignment and size of the GTT binding rather than assume
the current values on the object.
