Description of Change

There were several bits of code that needed to be revised so that the LCD display works on the adafruit-camera-esp32s3:

  • the backlight has to be turned on through the I/O expander, which is an AW9523 type
  • the VSCSAD register value was wrong, making the top part of the screen corrupt

This is tested on PyCam Rev C board.

per ladyada, a future rev of the camera board will ensure the LCD backlight is on without talking to the I/O expander so we may be able to back that code out in the future.

No problem, we can revert it when the hw is out
