/**
* Patch for pins_arduino.h (...\Arduino\hardware\arduino\avr\variants\mega\pins_arduino.h)
*
* These macros for the Arduino MEGA do not include the two connected pins on Port J (D13, D14).
* These macros for the Arduino MEGA do not include the two connected pins on Port J (D14, D15).
* So we extend them here because these are the normal pins for Y_MIN and Y_MAX on RAMPS.
* There are more PCI-enabled processor pins on Port J, but they are not connected to Arduino MEGA.
