Since introduction of PCIHP, it became problematic to
punch hole in PCI0._CRS statically since PCI hotplug
region size became runtime changeable.
So replace static hole punching with dynamically consumed
resources in a child device on PCI0 bus. i.e generate
PNP0C02 device as a child of PCI0 bus at runtime and
consume GPE0, PCI/CPU hotplug IO resources in it instead
of punching holes in static PCI0._CRS.
Tested with Windows XPsp3, Vista, Windows Server 2003, 2008, 2012r2.
PS:
Series adds several ASL like macros to simplify
code for dynamic generation of AML structures.

acpi: replace opencoded opcodes with defines
acpi: add PNP0C02 to PCI0 bus
acpi: consume GPE0 IO resources in PNP0C02 device
acpi: consume CPU hotplug IO resource in PNP0C02 device
pcihp: expose PCI hotplug MMIO base/length as properties of piix4pm
acpi: consume PCIHP IO resource in PNP0C02 device
