Pull tpm fix from Jarkko Sakkinen:
 "Revert commit e918e57 ("tpm_tis: Remove the HID IFX0102").

  Removing IFX0102 from tpm_tis was not a right move because both
  tpm_tis and tpm_infineon use the same device ID.

  A real fix requires quirks added to both drivers. It can probably wait
  until v5.9 as the bug has existed since 2006"
