In the TPM passthrough backend driver, modify the probing code so that we can check whether a TPM 1.2 or TPM 2 is being used and adapt the behavior of the TPM TIS accordingly. Move the code that tested for a TPM 1.2 into tpm_utils.c and extend it with test for probing for TPM 2. Have the function return the version of TPM found.
