Support for OP-TEE to parse the TPM eventlog. The eventlog format
is based on TCG specification [1], so we call this TCG framework.

To parse the eventlog and extend PCR's device is needed which
supports PCR's. This device can be TPM or any other HSM which
supports PCR like registers. Such a device can register itself
as a TCG provider for PCR information and ability to extend the
PCR's.
