RADIO: Make function declaration prototype

Add an explicit (void) to a functions without parameters,
in its declarations, this makes it an actual prototypes
which tells the compiler it gets no arguments,
instead of an unknown number of arguments.
This avoid possible build warnings, and possible
missaligments in the callers.
