In a later patch we will want to mark the flash memory as a
runtime services data memory range. This will allow a new runtime
services firmware block driver to read & write flash memory when
the OS has set up virtual memory protection.
Since this memory range will appear as runtime services data, we
need to adjust the limit when scanning for PCI window 32 down to
just below the flash device. If we don't adjust the limit, then
the algorithm in PopulateFwData will fail because it will see a
EfiGcdMemoryTypeSystemMemory memory range just below 4GB.
v2:
* This patch replaces the v1 patch:
"OvmfPkg/AcpiPlatformDxe/Qemu: Allow high runtime memory regions"

This should be more compatible with AML parsers in practice
since older versions of ACPICA's OS support would not accept
the previous OVMF format (despite being spec compliant).
(For example, on OpenBSD 5.2 it caused a kernel crash)
ACPICA has fixed this issue in:

Move these states from the DSDT to the SSDT. Override the default
configuration if the host has the following qemu commit:

Add PIIX4 properties to control PM system states.
This patch adds two things. First it allows QEMU to distinguish
between regular powerdown and S4 powerdown. Later separate QMP
notification will be added for S4 powerdown. Second it allows
S3/S4 states to be disabled from QEMU command line. Some guests
known to be broken with regards to power management, but allow to
use it anyway. Using new properties management will be able to
disable S3/S4 for such guests.
Supported system state are passed to a firmware using new fw_cfg
file. The file contains 6 byte array. Each byte represents one
system state. If byte at offset X has its MSB set it means that
system state X is supported and to enter it guest should use the
value from lowest 3 bits.

Represent the set of possible PCI link target IRQs with
Pcd8259LegacyModeEdgeLevel. This ensures that the 8259 Interrupt
Controller code in PcAtChipsetPkg will treat them as level-triggered too.

"FWDT" ("firmware data") is allocated as EfiReservedMemoryType, with
AllocateReservedPool(). <MdePkg/Include/Library/MemoryAllocationLib.h>
doesn't seem to provide direct access to EfiACPIReclaimMemory, but at this
point the former seems sufficient.
Based on SeaBIOS commit 2062f2ba by Gerd Hoffmann <kraxel@redhat.com>.
v3:
- coding style fixes:
- BDAT -> FWDT
- __packed -> #pragma pack(1)
- BFLD -> FIRMWARE_DATA, PCI_WINDOW
- Bfld -> FwData
- Ssdt.asl: changed license to 2-clause BSDL, paraphrasing Dsdt.asl

This patch adds Xen ACPI tables support to OVMF.

while keeping the Qemu and KVM support.

Update MADT processing for QEMU to add additional Local APIC
entries to the MADT.
The MADT is still built with a single Local APIC entry.
If the AcpiPlatformDxe driver determines that more processors
are available, then additional Local APIC entries are added
to the MADT at runtime.
