rfkill: add the WiMAX radio type

Teach rfkill about wimax radios.

Had to define a KEY_WIMAX as a 'key for disabling only wimax radios',
as other radio technologies have. This makes sense as hardware has
specific keys for disabling specific radios.

The RFKILL enabling part is, otherwise, a copy and paste of any other
radio technology.
