Pull tpm updates from Jarkko Sakkinen:
 "New features:

   - ARM TEE backend for kernel trusted keys to complete the existing
     TPM backend

   - ASN.1 format for TPM2 trusted keys to make them interact with the
     user space stack, such as OpenConnect VPN

  Other than that, a bunch of bug fixes"
