HACK: Herobrine: Reinit TPM INT GPIO

We noticed at some point after running the blobs that we started
getting TPM communication errors and realized that some QC blob was
reconfiguring this GPIO during execution.  We haven't debugged to
which blob actually does this, so basically reinitializing the TPM
interrupt GPIO excessively to get around this issue for now.
