[PATCH 11/12] nfc: st21nfca: mark ACPI and OF device ID tables as maybe unused

[Krzysztof Kozlowski]

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=]
