video: rockchip: Fix vop modes for rk3399

VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.

These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,

RK3288:

vopb_out: port {
	#address-cells = <1>;
	#size-cells = <0>;
	vopb_out_edp: endpoint@0 {
		reg = <0>;
		remote-endpoint = <&edp_in_vopb>;
	};
	vopb_out_hdmi: endpoint@1 {
		reg = <1>;
                remote-endpoint = <&hdmi_in_vopb>;
        };
        vopb_out_lvds: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&lvds_in_vopb>;
        };
        vopb_out_mipi: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi_in_vopb>;
        };
};

RK3399:

vopb_out: port {
         #address-cells = <1>;
         #size-cells = <0>;
         vopb_out_edp: endpoint@0 {
                reg = <0>;
                remote-endpoint = <&edp_in_vopb>;
         };
         vopb_out_mipi: endpoint@1 {
                reg = <1>;
                remote-endpoint = <&mipi_in_vopb>;
         };
         vopb_out_hdmi: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&hdmi_in_vopb>;
         };
         vopb_out_mipi1: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi1_in_vopb>;
         };
         vopb_out_dp: endpoint@4 {
                reg = <4>;
                remote-endpoint = <&dp_in_vopb>;
         };
};

here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.

The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.

Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.

Add the patch for fixing these vop modes for rk3399.
