hdata/tpmrel.c: add firmware event log info to the tpm node
This parses the firmware event log information from the
secureboot_tpm_info HDAT structure and add it to the tpm device tree
node.
There can be multiple secureboot_tpm_info entries with each entry
corresponding to a master processor that has a tpm device, however,
multiple tpm is not supported.
