ARM: integrator: switch Integrator platforms to use consolidated CLCD

This switches integrator platforms to use the consolidated CLCD
panel support, including the display capabilities.  These capabilities
prevent the unsupported BGR565 mode being selected, while still
allowing RGB5551, BGR5551 and RGB565 modes.
