[PATCH] arm64: dts: ti: k3-j784s4-mcu-wakeup: Configure wkup_uart0 with clock settings

[Bhavya Kapoor]

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.
