Remove the #10088 hotfix for Teensy 3.1-like Input:Club keyboards (#1…

…2870) * 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.
