Implement support for GetOperatingParamters notify phase
in SdMmcHcDxe driver. GetOperatingParameters notify phase
is signaled before we start card detection and initialization.
Code has been updated for both eMMC and SD card controllers to
take into consideration those new parameters. Initialization process
has been divided into 2 steps. In the first step we bring the link
up to the point where we can get card identification data(Extended
CSD in eMMC case and SWITCH command response in SD card case). This
data is later used along with controller capabilities and operating
parameters passed in GetOperatingParameters phase to choose preferred
bus settings in GetTargetBusSettings function. Those settings are later
on to start bus training to high speeds. If user passes incompatible
setting with selected bus timing driver will assume it's standard behavior
with respect to that setting. For instance if HS400 has been selected as a
target bus timing due to card and controller support bus width setting of
4 and 1 bit won't be respected and 8 bit setting will be chosen instead.

When assigning a physical PCIe device to a QEMU/KVM guest, PciBusDxe may
find that the extended config space is not (fully) implemented. In
LocatePciExpressCapabilityRegBlock(), "CapabilityEntry" may be read as
0xFFFF_FFFF at a given config space offset, after which the loop gets
stuck spinning on offset 0xFFC (the read at offset 0xFFC returns
0xFFFF_FFFF most likely as well).
Another scenario (not related to virtualization) for triggering the above
is when a Conventional PCI bus -- exposed by a PCIe-to-PCI bridge in the
topology -- intervenes between a PCI Express Root Port and a PCI Express
Endpoint. The Conventional PCI bus limits the accessible config space of
the PCI Express Endpoint, even though the endpoint advertizes the PCI
Express capability. Here's a diagram, courtesy of Alex Williamson:

0Ch) register.
This will lead to an issue that hard disk devices may not be found in the
non-S3 boot path for some AHCI controller capabilities.
More specifically, variable 'PortInitializeBitMap' will have the value
from 'Private->PortBitMap', which will be 0xFFFFFFFF in non-S3 boot path.
When the CAP register is of value 0x1 and PI register with value 0x4
(meaning port 2 is available), the current logic will only enumerate port
0. And the device attached behind port 2 will not be enumerated.
To address this issue, variable 'PortInitializeBitMap' will now take the
bitwise and result between 'Private->PortBitMap' and the value read from
the PI register.
Please note that there will be no function impact for S3 path, since in
this case, the bits being set in 'Private->PortBitMap' will be a subset
of the bits being set in the PI register. Their bitwise and operation will
still be the value of 'Private->PortBitMap'.

DEPEX from PEI storage stack.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1777
BootInRecoveryMode Ppi dependency should be removed from PEI storage stack
drivers. Besides recovery, more features are using the storage stack.
Platform can apply Ppi dependency in Recovery FV which contains full
storage driver stack. Platform storage stack modules, such as host
controller init PEI module, should also remove this dependency.

Refer to Uefi spec 2.8, the ResetData is valid while ResetStatus
is EFI_SUCCESS regardless of the ResetType is EfiResetPlatformSpecific
or not. So change the comments of NvmeShutdownAllControllers.

This commit will add the PEI BlockIO (2) PPIs support for AHCI mode ATA
devices.
More specifically, the driver will consume the ATA AHCI host controller
PPI for ATA controllers working under AHCI code within the system. And
then produces the below additional PPIs for each controller:
EFI PEI Recovery Block IO PPI
EFI PEI Recovery Block IO2 PPI
