Subject: [PATCH] tpm: add Revision ID field in the chip structure
TPM are shipped with a few read-only register from which we can retrieve
for instance:
- vendor ID
- product ID
- revision ID
Product and vendor ID share the same register and are already referenced
in the tpm_chip structure. Add the revision ID entry which is missing.
