net: rfkill: gpio: add DT support 

Allow probing rfkill-gpio via device tree. This hooks up the already
existing support that was started in commit 262c91ee5e ("net:
rfkill: gpio: prepare for DT and ACPI support") via the "rfkill-gpio"
compatible, with the "name" and "type" properties renamed to "label"
and "radio-type", respectively, in the device tree case.
