Subject: [PATCH v2 2/4] sh: remove unused __BUILD_IOPORT_SINGLE 'pfx' parameter

Previously __BUILD_IOPORT_SINGLE() accepted a "pfx" parameter, to which
__BUILD_IOPORT_PFX(), the only user of __BUILD_IOPORT_SINGLE(), passed
along its own "bus" parameter.  But users of __BUILD_IOPORT_PFX() supplied
nothing, so both "bus" and "pfx" are pointless.  Remove them.
