drivers: serial: ite_it8xxx2: add a dedicated priority symbol

Browse source 
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.

Initialization priority for the UART wrapper driver on ITE IT8XXX2,
must be set to a lower priority than the matching ns16550 device
(CONFIG_SERIAL_INIT_PRIORITY).
