util/cbmem: add parsing of TPM logs per specs
CBMEM can contain log in different forms (at most one is present):
- coreboot-specific format (CBMEM_ID_TPM_CB_LOG exported as
LB_TAG_TPM_CB_LOG)
- TPM1.2 format (CBMEM_ID_TCPA_TCG_LOG)
- TPM2 format (CBMEM_ID_TPM2_TCG_LOG)
The last two follow specifications by Trusted Computing Group, but until
now cbmem couldn't print them. These formats were added not so long ago
in:
- commit 4191dbf0c9a5 ("security/tpm: add TPM log format as per 1.2
spec")
- commit 53db677586e3 ("security/tpm: add TPM log format as per 2.0
spec")
These changes make cbmem utility check for existence of TPM1.2/TPM2 logs
in CBMEM and add code necessary for parsing and printing of their
entries.
