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]>
