hwmon: (xgene) Stop writing PCC shared memory signature

ACPI specification defines the generic PCC shared memory signature as
the PCC base signature ORed with the subspace ID.

ACPI 6.6 added clarification that the signature is populated by the
platform and verified by OSPM.

The PCC mailbox controller now validates the signature when the channel
is requested. Stop rewriting the signature before each command and
leave the platform-populated value intact.
