Non-discoverable devices need to be registered explicitly by the platform.
Introduce a helper library that takes care of this.
This implementation currently only supports registering devices that are
covered by one or more MMIO resources. The underlying protocol allows for
more flexibility than that, but this is currently sufficient for the use
cases that we know about.

Introduce a protocol that can be exposed by a platform for devices that
are not discoverable, usually because they are wired straight to the
memory bus rather than to an enumerable bus like PCI or USB.

Current memory attribute table implementation will only mark PE code
to be EfiRuntimeServicesCode, and mark rest to be EfiRuntimeServicesData.
However, there might be a case that a SMM code wants to allocate
EfiRuntimeServicesCode explicitly to let page table protect this region
to be read only. It is unsupported.
This patch enhances the current solution so that MemoryAttributeTable
does not touch non PE image record.
Only the PE image region is forced to be EfiRuntimeServicesCode for
code and EfiRuntimeServicesData for data.

PiSmmCore supports page level protection based upon the Memory Type
(EfiRuntimeServicesCode/EfiRuntimeServicesData) and PE image.
However, the Memory Type information is ignored in AllocatePool().
If a caller calls AllocatePool with EfiRuntimeServicesCode,
the final memory is still allocated as EfiRuntimeServicesData.
This patch supports AllocatePool with EfiRuntimeServicesCode.

According to AHCI Spec 1.3 GHC.AE bit description:
"The implementation of this bit is dependent upon the value of the
CAP.SAM bit. If CAP.SAM is '0', then GHC.AE shall be read-write and shall
have a reset value of '0'. If CAP.SAM is '1', then AE shall be read-only
and shall have a reset value of '1'."
Being in AhciMode, for proper operation it is required, that GHC.AE bit
is always set, before any other AHCI registers are written to. Current
AhciMode implementation, both in AhciReset() and AhciModeInitialization()
functions, set GHC.AE bit only depending on 'CAP.SAM == 0' condition,
assuming (according to the AHCI spec), that otherwise it has to be set
anyway. It may however happen, that even if 'CAP.SAM == 1', GHC.AE
requires updating by software.
This patch enables in AhciMode setting GHC.AE in case its initial value
is '0'. It fixes AHCI support for Marvell Armada 70x0 and 80x0 SoC
families. The change is transparent to all other platforms.

But in original code, there is a possible path which may have no such

UsbHubResetPort()->UsbHubSetPortFeature()->Stall(20)->UsbHubGetPortSt
