Fixes problems with ATMegaKeyboard and KeyAddr

Browse Source 
The correct KeyAddr type is not known to class ATMegaKeyboard
as key matrix dimentions (matrix_rows/matrix_columns) and
type KeyAddr are only defined in derived hardware classes. To deal with
this problem, some of the KeyAddr related methods are moved to
derived hardware classes.

The necessary boilerplate code is synthesized through a macro
ATMEGA_KEYBOARD_MATRIX_ACCESS_METHODS that is automatically included
by all derived classes of class ATMegaKeyboard through the already used
macro ATMEGA_KEYBOARD_CONFIG.
