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.

* This patch replaces the v1 patch:

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.

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.

Detect QEMU & Xen, and allow each to choose how to publish
the individual ACPI tables.
Currently both paths simply publish the tables unmodified.
