Yao, Jiewen fd46e831bc SecurityPkg: Update final event log calculation.
This patch updated final event log calculation based on
TCG EFI PROTOCOL rev9, 7.1.2 "All options implementation".
The previous logic is to save event to final event log
once GetEventLog() is called. 7.1.1 shows that we should
save event log to both normal even log area and final event
log area after GetEventLog() is called.
And there is no need to record TCG12 format log to final
event log area, and normal event log area can be BootServices
memory because OS will not access it directly.

Previously, NumberOfPCRBanks is calculated based on TPM

mask it via PCD. This causes the conflict between
HashAlgorithmBitmap and NumberOfPCRBanks.
So we move the NumberOfPCRBanks calculation based on

Yao, Jiewen d2de448338 Move Smbios measurement from TCG driver to Smbios driver.
This is patch to remove smbios measurement in TCG driver. There will be other patch to add it in Smbios driver.

The problem of current SMBIOS measurement is:
1) TCG drivers do not support SMBIOS3.0 table.
2) TCG drivers do not follow TCG platform spec on: "Platform configuration information that is automatically updated,
 such as clock registers, and system unique information, such as asset numbers or serial numbers,
 MUST NOT be measured into PCR [1], or any other PCR."

So we decide to move Smbios measurement from TCG drivers to Smbios driver.
