......................................................................

security/vboot: Add boot mode selection

* Add Measured Boot mode. Now a boot mode is selectable:
  -> Verified Boot (default)
  -> Verified Boot without TPM (antirollback protection is disabled)
  -> Verified & Measured Boot
* Measurements start in verstage for bootblock/verstage
  because of different bootblock sizes and issues related to it.
* prog_run() hook offers ability to measure every stage.
* Supported stages: romstage, postcar, ramstage, payload.
