pcmcia: use pcmica_{read,write}_config_byte
Use pcmcia_read_config_byte and pcmcia_write_config_byte instead of pcmcia_access_configuration_register. CC: netdev@vger.kernel.org CC: linux-wireless@vger.kernel.org CC: linux-serial@vger.kernel.org CC: Michael Buesch <mb@bu3sch.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
