drivers: display: features for ILI9341 driver

Replaced display-controller.yaml with lcd-controller.yaml
Deleted pixel format property, replacing it with the
property on lcd-controller.yaml. Replace ILI9XXX RGB macro
with PANEL RGB macro. Also, added condition to verify pixel
format is RGB565, BRG565 or RGB888, otherwise it will show error
