The driver can be built on ACPI and its .of_match_table uses
of_match_ptr(), thus annotate the actual table as maybe unused.

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it is not relevant here).
