Before the change, TPM FW upgrade will impact TPM2 ACPI PCR value because
TPM2 ACPI HID include FW version.
This change make the measurement before TPM2 HID fixup. So, after TPM FW
upgrade, the ACPI PCR record remains the same.

Pointer subtraction is not performed by pointers to elements of the same
array object. Such behavior is undefined by C11 standard and might lead to
potential issues, Refine pointer subtraction by first casting each pointer
to UINTN.

gEfiSecurityPkgTokenSpaceGuid.PcdTcgPhysicalPresenceInterfaceVer was
introduced to configure physical presence interface version. but test
or user needs to build different images to support different versions
separately as the PCD does not support Dynamic types.
This patch is to extend the PCD to support Dynamic types and add a
setup option in Tcg2ConfigDxe driver to configure the physical
presence interface version, the PCD needs to be DynamicHii type and
maps to the setup option.

Several issues exist in TCG2 PP
1. TCG2 PP use NVS PPRQ/PPRM as PP parameter as well as current
PP state cache. But it doesn't handle PP set failure case
2. TCG2 PP Submit TPM Operation Request to Pre-OS Environment forgets
to clean PPRM
3. Potential alignment issue

TPM2 hardware may support PTP FIFO/TIS interface
or PTP CRB interface. The original ACPI table only
handles PTP FIFO/TIS interface. This patch adds
PTP CRB interface support.
The current logic is that SMM driver will runtime
detect TPM device interface (CRB or FIFO/TIS) and
publish TPM2 table based on result.
It is compatible for old TPM2 FIFO/TIS device and
new TPM2 CRB device.
