[PATCHv3 5/5] net: rfkill: gpio: hard-code the gpio names

[Heikki Krogerus <heikki.krogerus@linux.intel.com>]

There is no need to dynamically generate the names. This
will fix a static checker warning..

net/rfkill/rfkill-gpio.c:144 rfkill_gpio_probe()
    warn: variable dereferenced before check 'rfkill->name'
