nfc: pn533: drop of_match_ptr from device ID table

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 might be not relevant here).  This
fixes compile warning (!CONFIG_OF):
