Move definition from tpm-interface.c to tpm_command.h, so that there is
no duplication. Also convert the ordinals in the tpm_input_header
declarations.
With the previous and this patch it will now be possible to convert TPM 1.2
functions to use tpm_buf_init(), which expect CPU native value for the
tag and ordinal arguments.

ORD ought not be used outside of drivers/char/tpm. TPM 1.2 trusted
keys does use this header but it should be eventually moved to
drivers/char/tpm (not done because of other stuff at this point).
