Subject: [PATCH] drm/i915: let pin routine figure out appropriate alignment
When this code got moved out of intel_pipe_set_base, it grew a forced
alignment of 256k, which wasn't always correct. Remove that and let the
pin routine figure out the correct alignment for the object (it should
do this in just about every case).
