Eliminate brake oscillations and grinding / crunching / ripping sound when using Pedal (Honda Pilot Only) (#475)

* Eliminate brake oscillations when using Pedal

* Simplified code

* syntax error fix

* Grinding code as applied to Honda Pilot only 

Each model may need its own setting due to USER_BRAKE noise disengagements

* correction: self.CP.carFingerprint instead of CP.carFingerprint

* Add Ridgeline to Pedal Grinding fix

Confirmed to work also on Ridgeline
