Espressif ESP32-S3 and ILI9488 Driver Configuration

[bonillml]

Hello all!

Recently, I've been toying around in Arduino IDE with my Espressif ESP32-S3 and wanted to connect and configure an LCD with a ILI9488 driver. However when I went to test one of the examples, after configuring all the required files, my Serial Monitor spits out dumps (pasted below).

Add this to your setup file:

#define USE_HSPI_PORT
