The calibration patches for MT7620 unnecessarily export symbols and populate never accessed function pointers. Remove all that and make functions static as the only place where each of those functions is called is within rt2800lib.c. Also make code more readable by fixing indentation, removing unnecessary parantheses and simplifying some instructions using shorthands here and there.
