According to TCG EFI Protocol Specification for TPM 2.0 family,
all events generated after the invocation of EFI_TCG2_GET_EVENT_LOG
shall be stored in an instance of an EFI_CONFIGURATION_TABLE aka
EFI TCG 2.0 final events table. Hence, it is necessary to trigger the
internal switch through calling get_event_log() in order to allow
to retrieve the logs from OS runtime.

Add support for measuring the MOK database and secure boot state into a
TPM, and do the same for the second stage loader. This avoids a hole in
TPM measurement between the firmware and the second stage loader.
