[POWERPC] Fix build failure for tqm8540 and sbc85xx defconfigs

The wrapper script didn't have entries for the TQM8540 board and the
SBC8548 or SBC8560 boards.  I've assumed that the TQM8540 console is
8250 based and not CPM based by looking at its defconfig.  There was
also a trailing * on the TQM8555 entry that I removed too.
