drm/xe/fbdev: use the same 64-byte stride alignment as i915
[ Upstream commit 4a36b339a14ae6f2a366125e3d64f0c165193293 ]
For reasons unknown, xe uses XE_PAGE_SIZE alignment for
stride. Presumably it's just a confusion between stride alignment and bo
allocation size alignment. Switch to 64 byte alignment to, uh, align
with i915.
This will also be helpful in deduplicating and unifying the xe and i915
framebuffer allocation.
