Pull tpmd fixes from Jarkko Sakkinen:
 "There has been a bunch of reports (e.g. [*]) reporting that when
  commit 5b359c7c4372 ("tpm_tis_core: Turn on the TPM before probing
  IRQ's") and subsequent fixes are applied it causes boot freezes on
  some machines.

  Unfortunately hardware where this causes a failure is not widely
  available (only one I'm aware is Lenovo T490), which means we cannot
  predict yet how long it will take to properly fix tpm_tis interrupt

  Thus, the least worst short term action is to revert the code to the
  state before this commit. In long term we need fix the tpm_tis probing
  code to work on machines that Stefan's patches were supposed to fix.

  With these patches reverted nothing fatal happens, TPM is fallbacked
  to be used in polling mode (which is not in the end too bad because
  there are no high throughput workloads for TPM).
