being buffered pass through the buffer macros. Removed the
straight-through signals from the layout, and renumbered the
vectors in the buffer cells, which no longer match the numbering
at the top level (unfortunately).
above housekeeping, because the upper GPIO pins are in the wrong
place relative to the new GPIO signal routing below the SoC.
Added pins for the pass-through connections. Unconnected/
unrouted OEB pins are still not present and probably should be
removed from the RTL.
Corrected one instance where a buffer had incorrectly been replaced
with a decap cell. Moved the left-hand side in by 0.6um to clear
the chip_io connections on the left-hand side. Corrected a small
DRC error in a route position at the bottom.
