Summary

This patch frees the timer pin used for the camera clock on Portenta carrier, and vision shield, allowing users to use it with tim. The pin doesn't strictly need to be reserved, as the timer module only deinitializes timers that were used. See b6649b9#commitcomment-160466116

Testing

Tested Portenta firmware still works.

stm32/boards: Update Arduino boards to reserve timers and fix USB PID.
b6649b9 
Reserve timers used for the camera, and fix USB PID because 0x055F is
reserved for MicroPython.
