Refactor TPM calls into vboot wrapper

Browse Source 
Try #2, now that ARM has the fix from http://gerrit.chromium.org/gerrit/4667

This cleans up the TPM calls inside vboot_reference.
* TPM calls share mode code between boot modes.
* Better handling for TPM_E_MUST_REBOOT, particularly in recovery mode.
* TAB screen shows current TPM versions.

No changes required to the wrapper API; these changes are internal to vboot.
