arm64: dts: ti: k3-am654: Populate power-domain property for UART nodes
Populate power-domain property for UART nodes, this is required for Linux to enable UART clocks via PM calls. Without this UART instances not initialized by bootloader (like main_uart1) fails to work in Linux. Also, drop current-speed property from main_uart1 and main_uart2 nodes as these UARTs are not initialized before Linux boots up and current speed is unknown.
