From: Duke Zhai <Duke.Zhai@amd.com>
BZ #:4640
In V3: Improve coding style follow edk2 C coding standard.
1.Remove macro definition extra underscores.
2.Putting some AMD copyright in the right place.
In V2: Improve coding style.
1.Remove the leading underscore and use double underscore at trailing in C header files.
2.Remove old tianocore licenses and redundant license description.
3.Improve coding style. For example: remove space between @param.
In V1:
This driver implements TPM 2.0 definition block in ACPI table and
registers SMI callback functions for Tcg2 physical presence and
MemoryClear to handle the requests from ACPI method.
