Enable OLED support for Teensy 3.2/LC (#7591)
* I2C_TIMEOUT is not defined on arm teensy * Work round teensy having different ChibiOS config options * Stash OLED conf files * update comment * update comment * Remove stm32 alias to allow teensy alt mode format code according to conventions [skip ci]
