driver: host_uart: Add host-uart device in npcx.

In order to prevent user turns on the pin-mux of devices has io-pads
unexpectedly, this CL added a new device definition for host uart
device. The pin-mux of host uart interface is enabled only if we set its
status as "okay" in dts file of board folder.

The following npcx7 drivers will meet:
1. Default status property of npcx devices with io-pads such as espi,
   pwm, uart, host uart and so on should be "disabled".
2. Switch pin-mux by changing status property to "okay" in dts file of
   board folder.
