v2: - fix implementation (lacked CONFIG_ inside IS_ENABLED...).
- drop dependency on CONSOLE_FLUSH_SUPPORT - that governs whether functions for explicit flushing should be built, and is not actually a requirement for allowing this implicit flushing, so the features should be selectable independently.
- add Simon's R-b to 1/2
1/2 is trivial prep. Motivation from 2/2:
When debugging, one sometimes only gets partial output lines or nothing at all from the last printf, because the uart has a largish buffer, and the code after the printf() may cause the CPU to hang before the uart IP has time to actually emit all the characters. That can be very confusing, because one doesn't then know exactly where the hang happens.
