mb/amd/birman: Don't select the console UART, default to y

Things with prompts should not use selects, but should instead default
to y. If there's a reason they need to be selected, they should be able
to be hidden when they're selected.

This isn't one of those cases where a select is needed, so set the
default to y instead.
