Support for ESP32S3 TTGO T-Display S3

Hello,

I'm attempting to get Nuttx up and running with LVGL on the ESP32S3 TTGO T-Display S3. ([product link](https://github.com/Xinyuan-LilyGO/T-Display-S3)). As far as I'm aware there isn't currently a configuration supplied for this board.

So far, I've been able to use `esp32s3-devkit:nsh`, as a base and enabling the USB-serial driver to use for nsh. Going forward, I was hoping to use the `ttgo_t_display_esp32:lvgl_fb` as a base for enabling support for the display, given they use the same `ST7789` display driver.

Perhaps there's a better way to approach this, or somebody has gone through this process previously? I'm quite new to Nuttx, so I may be overlooking something obvious.
