ice40: Add support for SB_GB_IO
During packing we replace them by standard SB_IO cells and create the
'fake' SB_GB that matches that IO site global buffer connection.
It's done in a separate pass because we need to make sure the nextpnr iob
have been dealt first so we have our final Bel location on the SB_IO.
