[GIT PULL] security subsystem: TPM updates for v4.19

[James Morris]

>From Jarkko:

" * Migrated away from PM runtime as explicit cmdReady/goIdle trasactions
    for every command is a spec requirement. PM runtime adds only a layer 
    of complexity on our case.
  * tpm_tis drivers can now specify the hwrng quality.
  * TPM 2.0 code uses now tpm_buf for constructing messages. I think Tomas
    Winkler has done the same for TPM 1.2. I'll start digging those
    changes from the patchwork in the near future.
  * Bug fixes and clean ups."
