shell: Fix builds for platforms without uart

Browse source 
We get build issues due to the removal of the Kconfig symbol
CONFIG_UART_SHELL_ON_DEV_NAME on platforms that didn't have a uart
set as we'd get a default value for those platforms.  Update the
Kconfig logic to only enable SHELL_BACKEND_SERIAL if we have
zephyr,shell-uart specified in the devicetree to address the issue.
