[PULL 56/68] hw/i386/acpi-build: Add support for SRAT Generic Initiator structures

[Michael S. Tsirkin]

From: Ankit Agrawal <ankita@nvidia.com>

The acpi-generic-initiator object is added to allow a host device
to be linked with a NUMA node. Qemu use it to build the SRAT
Generic Initiator Affinity structure [1]. Add support for i386.

[1] ACPI Spec 6.3, Section 5.2.16.6
