drivers: display: ili9xxx: generalize ILI display driver

Browse source 
Make driver generic for multiple ILI displays. The adopted strategy is
to share all driver code except register initialization, which has been
found to have some specific registers/values depending on the
controller.

The driver has been adjusted to support multiple compatibles.
