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

Add a new field in TcgNVS for PP operation user confirmation status,
instead of previous logic overriding Request. Previous logic causes
Get Pending TPM Operation Requested sub function return wrong value.

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.
