tpm_tis: Do not fall back to a hardcoded address for TPM2

Browse source

If the ACPI tables do not declare a memory resource for the TPM2
then do not just fall back to the x86 default base address.

Also be stricter when checking the ancillary TPM2 ACPI data and error
out if any of this data is wrong rather than blindly assuming TPM1.
