teensy-4.x: update pikron-bb configuration with PMSM control abilities

Browse Source 
This commit updates configuration pikron-bb (configuration for open
hardware experimental board) to support permanent magnet sychnronous
motor control. This includes setup of PWM, GPIO and ADC peripherals.

Required follow up changes are done to pinout definition.
