pc: set the OEM fields in the RSDT and the FADT from the SLIC 

The Microsoft spec about the SLIC and MSDM ACPI tables at
<http://go.microsoft.com/fwlink/p/?LinkId=234834> requires the OEM ID and
OEM Table ID fields to be consistent between the SLIC and the RSDT/XSDT.
That further affects the FADT, because a similar match between the FADT
and the RSDT/XSDT is required by the ACPI spec in general.

This patch wires up the previous three patches.

For data=, only data
portion of the table is used, all header information is specified in the
command line.
If a SLIC table is supplied to QEMU, then the SLIC's oem_id and oem_table_id
fields will override the same in the RSDT and the FADT (a.k.a. FACP), in order
to ensure the field matches required by the Microsoft SLIC spec and the ACPI
spec.
