Changes since v2:
* use dependency auto generation for *.dsl files
* hide DEVICE(PRES) from UI
* add comments to document holes punched in CRES
* reduce ifdeffenery by moving CPU hotplug defines to
a dedicated header shared between C and ASL files
* other odd changes requested by "Michael S. Tsirkin" <m...@redhat.com>
Changes since v1:
* renamed hotplug.c/.h to cpu_hotplug.c/.h
* make all prefixes acpi_cpu_hotplug and AcpiCpuHotplug
* updated docs/specs/acpi_cpu_hotplug.txt with Q35's IO port range
* exclude CPU/PCI/GPE IO ranges from resources advertised
in PCI bus _CRS
* advertise CPU hotplug IO range using ACPI Device(ACPI0004)._CRS
object.
* change Q35 IO port ase from 0xa18 to 0xcd8, to avoid increasing
fragmentation of PCI bus IO space
* replaced runtime IO port setting with compile time one, since
port mapping is hadcoded and there is not real need to set it
dynamically.
* Use the same headers for C and ASL code so that port/length
values won't be duplicated.
* Fix deps for ACPI tables, so that thay would be rebuild when
included files are touched. (Added only includes, I've touched,
it's not complete but a good start anyway)
Tested with RHEL6, WS2012R2, WS2003
