Add assigned clocks for DSS, DT node for DisplayPort PHY and pinmux for DP HPD. Add the clock frequency for serdes_refclk. Add the endpoint nodes to describe connection from: DSS => MHDP => DisplayPort connector. Also add the GPIO expander-4 node and pinmux for main_i2c4 which is required for controlling DP power. Set status for all required nodes for DP-0 as "okay".
