The config option doesn't make any sense anymore
when building a multiimage barebox. With a proper
DT built into the image we don't need the ODMdata
mechanism to find the debug UART anymore.

- This is the first serial console that gets activated by barebox.
- Normally each board vendor should program a valid debug UART into
- the ODMdata section of the boot configuration table, so it's a
- reasonably good bet to use that.
- If you know your ODMdata is broken, or you don't wish to activate
- any serial console at all you can override the default here.
