hw/tpm: Move DEFINE_PROP_TPMBE() macro to 'tmp_prop.h' local header

We are going to make "tpm_util.h" publicly accessible by
moving it to the include/ directory in the next commit.
The DEFINE_PROP_TPMBE() macro is only meaningful for the
TPM hardware files (in hw/tpm/), so keep this macro in a
local header.
