ADB keyboard not working in xmon

[Olaf Hering]

What is the best way to let do_initcalls wait until the adb probing task
has finished when xmon is enabled and system console is not on serial?
The patch below leads to a dead keyboard without the delay,
or without adb_sync as cmdline option and CONFIG_XMON_DEFAULT=n.
