Incorrect PWM pin on Micro schematic

[per1234]

The schematic for the Arduino Micro:
https://www.arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
Which is linked from the product page:
https://store.arduino.cc/arduino-micro

Shows that Arduino pin 4 (PD4) has PWM. In fact that should be Arduino pin 3 (PD0).

This information is documented correctly everywhere else I have checked, including the Leonardo documentation.

Originally reported at http://forum.arduino.cc/index.php?topic=507716

In a way, this was previously reported at #1373 but that issue assumes the schematic was correct and thus recommended incorrect edits to the documentation.

The schematics should be fixed now.
