[PATCH 6/6] tests/avocado: Add tests booting YAMON ROM on MIPS Malta machines

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Add quick tests booting YAMON:

YAMON does some endian-swapped acceses on the ISD<->PCI CFG/DATA
registers. These tests are useful to debug cross-endianness issues,
in particular on big-endian host.
