Add high-frequency spindle output option. Minor parking motion re-factoring.

Browse Source 
- Some laser controllers were reported to need a very high PWM
frequency. Added a line to enable this in cpu_map.h, if needed.

- Cleaned up some of the parking code. Mostly just editing the comments.

- Moved the accessory state resetting after the initial parking
retract. Should ensure the accessory state is properly handled upon an
aborted parking restore. Not certain if this was a problem before
though. Just to be sure.
