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.
