[PULL 35/46] bios-tables-test: Add complex SRAT / HMAT test for GI GP

["Michael S. Tsirkin" <mst@redhat.com>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Add a test with 6 nodes to exercise most interesting corner cases
of SRAT and HMAT generation including the new Generic Initiator
and Generic Port Affinity structures.  More details of the
set up in the following patch adding the table data.
