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. Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>
