Gather all the TPM1 definitions and structures in the internal header file drivers/char/tpm/tpm.h into the command header. In addition, bring in the single RNG structure from tpm-interface.c. The definitions moved to these files correspond to the TCG specification for TPM 1 family: TPM 1.2 Main Specification - https://trustedcomputinggroup.org/resource/tpm-main-specification/ Signed-off-by: Daniel P.
