efi-api: check the EFI_TCG2_FINAL_EVENTS_TABLE in efi_has_tpm2()

The EFI firmware may provide the TPM2 event log using
EFI_TCG2_FINAL_EVENTS_TABLE stored in EFI configuration table,
instead of the ACPI Table TPM2.

If the ACPI Table TPM2 doesn't exist, try to check whether
EFI_TCG2_FINAL_EVENTS_TABLE is available or not.
