partitions: efi: register guid device parameter for disk GUID
We already register an nt_signature parameter for MBR partitions.
Register an equivalent guid parameter for GPT partitions as well.
This is less critical because disk GUID isn't used for root=
Linux boot argument computation, as each partition has its own
PARTUUID. It's still useful to allow shell scripts to check
against it to detect e.g. a factory flash image.
