tpm: Move TPM2 specific definitions to the command header

Browse Source 
Gather all the TPM2 definitions and structures in the internal header
file drivers/char/tpm/tpm.h into the command header, including:
 - Command codes, return codes and definitions from the public and
internal tpm.h files.
 - Structures defined in numerous TPM driver C modules.

The definitions moved to these files correspond to the TCG specification
for TPM 2 family:

TPM 2.0 Library
