feat(spm): add tpm event log node to spmc manifest

Add the TPM event log node to the SPMC manifest such that the TF-A
measured boot infrastructure fills the properties with event log address
for components measured by BL2 at boot time.
For a SPMC there is a particular interest with SP measurements.
In the particular case of Hafnium SPMC, the tpm event log node is not
yet consumed, but the intent is later to pass this information to an
attestation SP.
