This commit adds the assigned-clocks and assigned-clock-parents properties for wkup_uart0 in J784S4. Specifically, the assigned-clocks property is set to reference the clock identified by "wkup_usart_mcupll_bypass_out0", ensuring the UART operates with the correct clock source. The assigned-clock-parents property specifies "wkup_usart_clksel_out0" as the parent clock. This configuration is critical for establishing the proper clocking hierarchy, enabling the UART device to function reliably across different baud rates.
