i386: add ACPI table files from seabios

This adds ASL code as well as scripts for processing it,
imported from seabios git tree
commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd

Will be used for runtime acpi table generation.

Note:
This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the
side of caution and include them.

Affected SeaBIOS files (GPLv2+ license headers added)
<http://thread.gmane.org/gmane.comp.bios.coreboot.seabios/5949>:

 src/acpi-dsdt-cpu-hotplug.dsl
 src/acpi-dsdt-dbug.dsl
 src/acpi-dsdt-hpet.dsl
 src/acpi-dsdt-isa.dsl
 src/acpi-dsdt-pci-crs.dsl
 src/acpi.c
 src/acpi.h
 src/ssdt-misc.dsl
 src/ssdt-pcihp.dsl
 src/ssdt-proc.dsl
 tools/acpi_extract.py
 tools/acpi_extract_preprocess.py

Each one of the listed people agreed to the following:

> If you allow the use of your contribution in QEMU under the
> terms of GPLv2 or later as proposed by this patch,
