Add the OPP tables for DSI and MDP based on the perf state/clk
requirements, and add the power-domains property to specify the
scalable power domain.

as commented on "[v3,03/17] arm64: dts: sdm845: Add OPP table for all qup
devices" (https://patchwork.kernel.org/patch/11514693/) this table should
probably be inside the 'mdp' node.

right, I will move this and the below table inside the device nodes.

+

+

+				opp-hz = /bits/ 64 <358000000>;
+				required-opps = <&rpmhpd_opp_nom>;
+			};
+		};
+

depending on the outcome of the discussion mentioned above this might have
to move into the 'dsi0' node.
