dt-bindings: display: rockchip: Add schema for RK3588 DW DSI2 controller



The Display Serial Interface 2 (DSI-2) is part of a group of communication
protocols defined by the MIPI Alliance. The RK3588 implements this
specification in its two MIPI DSI-2 Host Controllers that are based on a
new Synopsys IP.
