drivers: serial: ite_it8xxx2: add a dedicated priority symbol

The uart_ite_it8xxx2 is relying on a node that depends on a matching
ns16550 symbol, such as:

ite_uart1_wrapper: uartwrapper@f02720 {
        compatible = "ite,it8xxx2-uart";
	...
        uart-dev = <&uart1>;
};

But the two are currently setup to initialize at the same level and
priority. Add a dedicated priority symbol so that the wrapper device is
always initialized after the main one, regardless of the linker order.
