exynos/snow: Configure UART peripheral during console initialization.
For Exynos platforms, the UART component on pinmux must be first selected and configured. This should be done as part of UART console initialization. Note, that the current implementation hard-codes the device index as UART3, while the base port can be assigned to different device in Kconfig. This will be fixed later. Verified to work on armv7/snow.
