Issue LCD display st7789v2, not working on esp32s3 n16r8 with camera

[phituong]

Dear all,
I had an issue for displaying video streaming (ov5640) on LCD st7789v2 (320x240) with esp32s3 n16r8.
I tried to run this example in /driver/video/capture ](https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/drivers/video/capture)

The camera video worked well, but LCD display nothing. I check wire connection physically, and it connected correctly.

Here are results of running the code:
