OvmfPkg/SMBIOS: Add QEMU support to OVMF SMBIOS driver
Locate QEMU SMBIOS data in fw_cfg and install it via the
SMBIOS protocol.
Starting with qemu-2.1, on pc/x86 machines of type >= 2.1, full
SMBIOS tables are generated and inserted into fw_cfg (i.e., no
per-field patching of locally generated structures is required).
Aside from new code to extract a SMBIOS blob from fw_cfg, this
patch utilizes the pre-existing infrastructure (already used by
Xen) to handle final SMBIOS table creation.
