Added board hardware driver support for the Adafruit U4 breakout board.
Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.
Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).
