Leif Lindholm fe93b3745f DynamicTablesPkg/FdtHwInfoParserLib: add missing resolutions/includes
FdtHwInfoParserLib does not explicitly call out its dependencies on
BaseLib/BaseMemoryLib, which is currently hidden when EmbeddedPkg FdtLib
pulls them in instead. But that is going away, so make the necessary
explicit references and add missing include statements.

Pierre Gondois d8aa665b31 DynamicTablesPkg: FdtHwInfoParserLib: Move IRQ map to arch folder
The interrupts property in DT is arch specific.
Move the current implementation and the way to decode the property
to the Arm folder to prepare for other architecture support.

Pierre Gondois a7cc72c360 DynamicTablesPkg: FdtHwInfoParserLib: Make Serial Port parser arch neutral
To allow other architectures to potentially re-use the serial port
parser and make the code arch neutral, remove the Arm prefixes.

Pierre Gondois f16817ec84 DynamicTablesPkg: FdtHwInfoParserLib: Make Pci parser arch neutral
To allow other architectures to potentially re-use the serial port
parser and make the code arch neutral, remove the Arm prefixes.
Also remove the check searching for a GIC version.

Pierre Gondois 4bb08e8863 DynamicTablesPkg: FdtHwInfoParserLib: Refactor to prepare for other archs
To allow other architectures to potentially re-use the serial port
parser and make the code arch neutral, make the MainDispatcher()
function arch specific.

Other architectures can choose which parse/dispatcher are desired
to be called through the configuration of the HwInfoParserTable.

step to support other architectures.

Pierre Gondois deb01dfd7f DynamicTablesPkg: Add FdtHwInfoParser library
Hardware information parser is an optional module defined
by the Dynamic Tables Framework. It can either parse an
XML, a Device Tree or a Json file containing the platform
hardware information to populate the platform information
repository.

FdtHwInfoParser library is an instance of a HwInfoParser
that parses a Device Tree and populates the Configuration
Manager Platform information repository.

FdtHwInfoParser library is aimed at providing a solution
for generating ACPI tables for Guest Partitions launched
by virtual machine managers (VMMs). One such use case is
Kvmtool where the Device Tree for the Guest is passed on
to the firmware by Kvmtool. The Configuration Manager for
Kvmtool firmware shall invoke the FdtHwInfoParser to parse
the Device Tree to populate the hardware information in
the Platform Info Repository. The Kvmtool Configuration
Manager can the process this information to generate the
required ACPI tables for the Guest VM.

This approach also scales well if the number of CPUs or
if the hardware configuration of the Guest partition is
varied.

FdtHwInfoParser thereby introduces 'Dynamic Tables for
Virtual Machines'.
