Add Lilygo T-Embed to st7789v display config. (#5337)
* Add Lilygo T-Embed to st7789v display config. * Move all configuration into the Python code. Add presets for TTGO. All preset configuration can be overridden. * Add Adafruit S2 pin presets * Add test * Add funhouse pins. Co-authored-by: Keith Burzinski <kbx81x@gmail.com> * Keep ordering of options consistent * Remove unused declarations --------- Co-authored-by: Keith Burzinski <kbx81x@gmail.com>
