drivers/tpm: Add TPM ramstage driver for devices without vboot.

Logic: If vboot is not used and the tpm is not initialized in the
romstage makes use of the ramstage driver to initialize the TPM
globally without having setup calls in lower SoC level implementations.

* Add TPM driver in ramstage chip init which calls the tpm_setup
  function.
* Purge all occurrences of TPM init code and headers.
* Only compile TIS drivers into ramstage except for vboot usage.
* Remove Google Urara/Rotor TPM support because of missing i2c driver
  in ramstage.
