While assigning the sequence number to subsystem instances by reading the

Since U-boot EFI implementation is getting richer it makes sense to
add support for EFI_TCG2_PROTOCOL taking advantage of any hardware TPM
available on the device.
This is the initial implementation of the protocol which only adds
support for GetCapability(). It's limited in the newer and safer
A following patch introduces EFI_TCG2_PROTOCOL.
