Display: STM32: display in not working on stm32f429i_disc1

[ajarmouni-st]

Describe the bug The drivers/display sample gives random noise on the screen. LVGL samples, modules/lvgl/demos & subsys/display/lvgl, give distorted frames.

• What target platform are you using? stm32f429i_disc1 board
• What have you tried to diagnose or workaround this issue? Found a fix to ili9341 driver that must be applied on top of PR #66271. PR #66271 alone gives a white screen.
• Is this a regression? No info

To Reproduce Steps to reproduce the behavior:

1. cd ~/zephyrproject/zephyr
2. west build -p always -b stm32f429i_disc1 samples/drivers/display
3. west flash

Expected behavior Correct display of frames.

Impact showstopper

@fabiobaltieri PR #66271 alone does not fix this issue, PR #68105 is needed as well. Will reopen.
