zephyr: Get UART console device from devicetree instead of Kconfig.

MaureenHelm · dpgeorge · commit 1e5df0982aea · 2022-01-06T14:09:39.000+11:00
Updates the Zephyr port to get the UART console device from devicetree
instead of Kconfig. The Kconfig option CONFIG_UART_CONSOLE_ON_DEV_NAME
was removed in Zephyr v2.7.0.
