* Remove the #10088 hotfix for K20x MCU:s.
It seems to _cause_ the issue it intended to solve there.
* Cleaner way of removing #10088 hotfix.
Now only affects Ergodox Infinity, Whitefox and K-type, though.
Switches over Ergodox Infinity to the `IC_TEENSY_3_1` board, since that
was a nice place to implement the `restart_usb_driver` override.
However, I would guess this issue is present for other K20x/Teensy 3.1
boards as well...
* Fix comment regarding `IC_TEENSY_3_1` for all keyboards using it.
* Initial work for consolidation of board files and default ChibiOS configs.
* Migrate F401/F411 black pills for testing.
* Add early init bootloader jump flag.
* Add support for I2C in order to use i2c_scanner keymap.
* Add F401/F411 HSE bypass to get things booting.
* Exempt "hooked" ChibiOS conf files from updater script.
* Fix up ordering for bootloader_defs file check.
* Match previous $(KEYBOARD_PATHS) value for Proton-C, updated for all board configs.
