3.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <[email protected]>

commit 6d8ea7de3f5035610f3bfacbe35e7b71ad1e4663 upstream.

Apply the same logic as CI to SI for setting up the
display tiling parameters.  The num banks may vary
per tiling index just like CI.
