[PATCH] tests/acceptance: Test PMON with Loongson-3A1000 CPU

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Test the PMON firmware. As the firmware is not redistributable,
it has to be downloaded manually first. Then it can be used by
providing its path via the PMON_PATH environment variable:

  $ AVOCADO_ALLOW_UNTRUSTED_CODE=1 \
    PMON_PATH=/images/pmon \
    avocado --show=app,console \
      run -t machine:loongson3-virt tests/acceptance
