When booting with SME active, EFI tables must be mapped unencrypted since they were built by UEFI in unencrypted memory. Update the list of tables to be checked during early_memremap() processing to account for the EFI TPM tables.
This fixes a bug where an EFI TPM log table has been created by UEFI, but it lives in memory that has been marked as usable rather than reserved.
