* Error out when Solenid pin is not defined
Instead of defaulting to a (literally) random pin, error out instead. Because this pin may be used, or because that pin may not be exposed, or may not exist.
* Remove 'SOLENOID_ACTIVE' setting since it's not used
* Update documentation
* provide means to turn on RTP mode and set the amplitude
* new keycode HPT_CONT to turn RTP off/on
* introduce new keycodes HPT_CONI, and HPT_COND for Haptic Continuous Increase and Decrease
* support for continuous mode amplitude increase and decrease
* code cleanup
* update docs to reference new keycodes and functionality
* don't touch the keymaps
* add function prototypes
* add proper guards
* cleanup guards
* remove extra reserved
* initial work to add eeprom to haptic feedback and decouple the feedback process from keyboards
* Haptic feedback enhancements: on/off toggle working, feedback order working
todo:
-work on modes switching
-get modes switching to save to eeprom
* haptic enhancement - eeprom and modes added
* Added set and get functions for haptic feedback
* initial implementation of solenoids under haptic feedback
* changed eeprom to 32 bits to reserve blocks for future features
* start documentation of haptic feedback
* change keycode per comment from reviewers
* typo fixes
* added eeprom for solenoid configs
* added solenoid and docs
* Add/fix default parameters configs, improve docs
* more doc cleanup
* add in solenoid buzz toggle, clean up doc
* some fixes for error in compiling solenoid
* fix a chibios specific i2c read function and added one for AVR controllers in DRV2605L.c
* fixes for avr side issues
* update keymap
* fix keymap compile error
* fix bugs found during solenoid testing
* set pin that is not powered during bootloader
* added warning about certain pins on the MCU may trip solenoid during DFU/bootloader
