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.

IT8XXX2 uses shared ns16550.c driver which does not
|
|
provide a power management callback, so create driver
|
|
to handle IT8XXX2 specific UART features. In addition
|
|
to use pm_action_cb, we also need to make some setting
|
|
at uart_it8xxx2_init.

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).
