dts: bindings: display: gc9x01x: Update example and documentation

Update the GC9X01X display driver binding documentation with the current MIPI DBI SPI binding structure. The old example used direct SPI device binding which is now deprecated in favor of the MIPI DBI API. Signed-off-by: Benjamin Geiger <[email protected]>

-  GC9X01X display driver.
-
-  This driver implements support for various GC9X01X graphics
-  controllers and different display sizes. It has been validated
-  for following controllers:
-   - GC9101A: (Waveshare 240x240, 1.28inch round lcd display 240x240)
-
-  Here is an example to define a display interface:
-
-  &spi2 {
-    gc9a01a_lcd: gc9a01a_lcd@0 {
-      compatible = "galaxycore,gc9x01x";
-      reg = <0>;
-      spi-max-frequency = <100000000>;
-      cmd-data-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>;
-      reset-gpios = <&gpio0 8 GPIO_ACTIVE_LOW>;
-      pixel-format = <PANEL_PIXEL_FORMAT_RGB_565>;
-      width = <240>;
-      height = <240>;
