DRVOFF does not need to be connected to MCU #28

DRVOFF can be connected to GND to keep motor driver constantly enabled.

This would allow to free up one isolator pin and allow to use smaller 2-channel isolator.

Removed the DRVOFF pin connections, however I still argue for having 3 4-channel isolators as three of the outputs are needed at the top of the board. Replacing it with a 2 channel isolator would needlessly lengthen the signal traces (and also cut into the copperless area inbetween the isolated grounds).
