nfc: st21nfca: mark ACPI and OF device ID tables as maybe unused 

The driver can match either via OF or ACPI ID tables.  If one
configuration is disabled, the table will be unused:

    drivers/nfc/st21nfca/i2c.c:593:34: warning:
        ‘of_st21nfca_i2c_match’ defined but not used [-Wunused-const-variable=]
