[PATCH v4 6/6] MdePkg/Pci22.h: Deprecate out-of-Spec IncompatiblePciDevice macros

[Ruiyu Ni <ruiyu.ni@intel.com>]

DEVICE_ID_NOCARE is defined as 0xFFFF but Spec says (UINT64) -1
should be used to match any VendorId/DeviceId/RevisionId/
SubsystemVendorId/SubsystemDeviceId.

PCI_BAR_OLD_ALIGN/PCI_BAR_EVEN_ALIGN/PCI_BAR_SQUAD_ALIGN/
PCI_BAR_DQUAD_ALIGN are defined but Spec doesn't have such
definitions.

PCI_BAR_ALL is defined as 0xFF but Spec says (UINT64)-1 should be
used to match all BARs.

PCI_ACPI_UNUSED and PCI_BAR_NOCHANGE are defined as 0 which
compliant with Spec but the name is too general and causes confusing.
IncompatiblePciDeviceSupport could directly use 0.

All of the above macros are marked as deprecated.
