[GIT PULL] tpmdd updates for v4.16

[Jarkko Sakkinen]

Hi James,

Sorry for a late PR.

Summary of the content:

* Reduced polling delays in tpm_tis.
* Support for retrieving TPM 2.0 Event Log through EFI before
  ExitBootServices.
* Replaced tpm-rng.c with a hwrng device managed by the driver for each
  TPM device.
* TPM resource manager synthesizes TPM_RC_COMMAND_CODE response instead
  of returning -EINVAL for unknown TPM commands. This makes user space
  more sound.
* CLKRUN fixes:
  * Keep #CLKRUN disable through the entier TPM command/response flow.
  * Check whether #CLKRUN is enabled before disabling and enabling it
    again because enabling it breaks PS/2 devices on a system where it
    is disabled.
