Fixes to H-Bridge2Go Implementation

Pins of PWM and DIS were swapped (also wrong labels on PCB):
PWM is on P2.10 = Arduino Pin 11
DIS is on P2.11 = Arduino Pin 10

Fixes to mapping_pin_PWM4:
- Pin 8 was mapped to non-existing index 10 -> changed to index 0
- Added entry for Pin 11 (PWM of H-Bridge) -> mapped to index 1
