    hw/misc/mps2-scc.c: fix scc_partno field width

    Increase the extract32 length from 8 to 12. The Primary part number is
    defined as bits[15:4] by the "SSE-310 with M85 and U55 FPGA"
    documentation. For example for the mps3-an547, 0x547 is 12 bits but we
    only return 8 bits right now.
