EFI TrEE Protocol uses the same protocol GUID as EFI TCG2 protocol, and
defines the capability structure version 1.0. Hence, the structure and
name are all align the EFI TrEE Protocol.

Certain AMI BIOS (Intel NUC5i3MYBE BIOS version 0037) may make the strict
check on the last 3 arguments passed to get_event_log() and don't expect
NULL pointers are passed. In order to work around this failure
(EFI_INVALID_PARAMETER), pass them even though we really don't use it.

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.
