Older gcc versions are unhappy that some types declared by TPM 1.2
headers are re-declared by TPM 2 headers. All of these types have
the same UINT32 datatype and we can avoid having the re-declared
by introducing TPM_HAVE_TPM2_DECLARATIONS and inlcuding the TPM2
headers first and then the TPM 1.2 headers where we then do not re-
declare those datatypes that are clashing.
