Main_uart5 node defined in the top-level J722S SoC dtsi file is incomplete and may not be functional unless it is extended with pinmux information. As the pinmux is only known at the board integration level, main_uart5 node should only be enabled when provided with this information. Thus, add pinmux for main_uart5 and enable it in the board dts file.
