ArmVirtPkg: Clear TPIDR_EL0 before early HOB lookups
TPIDR_EL0 is used to hold the PrePi HOB list pointer, but its reset
value is unknown. Some early boot paths can call GetHobList() before
PrePiMain() creates and installs the HOB list.
Clear TPIDR_EL0 at the SEC entry point so those early lookups see NULL
rather than an invalid pointer.

OvmfPkg/MapMmioLib: Introduce a library for mapping MMIO regions
Introduce MapMmioLib to add MMIO regions to the GCD memory map.
MapMmioMemory() normalizes the requested range to page boundaries, adds
missing MMIO descriptors, and updates attributes for new and existing MMIO
descriptors. Existing descriptors of any other type are reported as
conflicts.

OvmfPkg/MapMmioLib: Support runtime drivers
Allow MapMmioLib to be consumed by DXE_RUNTIME_DRIVER modules.
MapMmioMemory() depends on DXE services, so it cannot map new
ranges after ExitBootServices(). Return EFI_ACCESS_DENIED when
called at runtime.
This allows runtime drivers such as
ArmVirtPkg/Library/KvmtoolRtcFdtClientLib to use MapMmioLib for
boot-time MMIO setup.

ArmVirtPkg: Include MapMmioLib in ArmVirt.dsc.inc
Add the MapMmioLib instance to the ArmVirt DXE_DRIVER library class
list so DXE drivers can map MMIO regions through the common helper.
Also add the runtime-driver library class mapping in ArmVirt.dsc.inc
so that runtime modules like KvmtoolRtcFdtClientLib can use
MapMmioLib.

ArmVirtPkg/KvmtoolRtcFdtClientLib: Use MapMmioLib for MMIO mapping
Replace the local RTC MMIO mapping sequence with MapMmioMemory(), while
keeping the explicit GCD allocation so the RTC page remains owned by the
driver image handle.
This reuses the common MMIO mapping path for GCD attributes.
Also update the incorrect error code documentation to reflect that
EFI_NOT_FOUND can be returned if the GCD space is not found and
drop the depex on gEfiCpuArchProtocolGuid as this is now done
by MapMmioLib which is where the Cpu Arch protocol is utilised.

OvmfPkg/FdtPciHostBridgeLib: Use MapMmioLib for MMIO mapping
Replace the local GCD MMIO mapping helper with MapMmioMemory() when
mapping the PCI ECAM region and the translated I/O MMIO window.
This keeps the FDT PCI host bridge code aligned with the common MMIO
mapping helper and avoids duplicating AddMemorySpace() and
SetMemorySpaceAttributes() handling.

ArmVirtPkg: Add early FDT 16550 serial port probe library
Fdt16550SerialPortHookLib does not provide a constructor and
expects SerialPortLib to call PlatformHookSerialPortInitialize().
Add an early FDT 16550 serial port probe library that invokes the
platform serial hook from its constructor. This allows the FDT to be
parsed early, the 16550 serial port base address to be extracted, and
the serial port PCD to be populated. It is needed during early boot so
the serial port memory map can be set up using the populated serial
port PCD.
The probe library wraps the hook call in its constructor instead of
reusing PlatformHookSerialPortInitialize() directly. This avoids
duplicate global definitions in modules that already link against the
PlatformHookLib instance.

ArmVirtPkg: Refactor memory map configuration for Kvmtool Guest VM
Refactor the memory mapping configuration for Kvmtool Guest VM to
only setup the memory map for the System Memory, FV and the Serial
Port.
The memory mappings for he remaining devices are expected to be
configured by the respective drivers, this could be done as part
of the DXE drivers itself or using a Probe Library that adds the
device memory regions to the memory map.
The only special cases that remain are the System Memory, FV and
the Serial Port for which the memory mappings are created by the
KvmtoolVirtMemInfoLib. The memory mapping for the Serial port
is added as it is utilised for logging before the DXE driver
is loaded.
