Michael Kubacki 50e1432a40 PrmPkg: Add initial PrmSsdtInstallDxe module
Adds a new module that installs a PRM SSDT.

Note: A library class would allow a high degree of flexibility for
platforms that choose:
  1. To not install a PRM SSDT at all (using a NULL library instance)
  2. To install a specific PRM SSDT implementation

However, it is implemented as a driver since build tools are not
linking ACPI tables to drivers from linked library classes.

Liu ef05955996 PrmPkg: Publish PRM operation region to support PRM ACPI _DSM invocation
A PRM Handler has a 1-to-1 mapping to the corresponding _DSM method.
The UUID of the _DSM Method will be passed by the ASL code to the
OpRegionHandler which will look up the PRMT Table to extract the
pointer of the corresponding PRM Handler.

PRM loader pre-builds an SSDT that includes this PRM operation region.
In boot time, the PRM loader will load and publish this SSDT, so that
in OS runtime ACPI _DSM can invoke the PRM handler by pass the UUID to
PRM operation region.

The pre-build SSDT also includes a PRMT device as a Sample ACPI _DSM to
invoke PRM handler.

Michael Kubacki 3f7af17c6b PrmPkg/PrmConfigDxe: Add initial driver
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3812

This driver serves as a generic PRM configuration driver. Its primary
role is to prepare PRM resources published by PRM module configuration
libraries for OS runtime. As such, it locates all PRM Configuration
Protocol instances and consumes the information to ready those resources.

For example, set runtime memory attributes on MMIO ranges and convert
physical addresses to virtual addresses in PRM buffers.
