Revert "dm: core: Simplify dm_probe_devices()"

Browse source 
Unfortunately this change was not safe as some devices are bound before
relocation, but we don't want to probe them.

It causes 'raise: Signal # 8 caught' on jerry.

Move the bootstage timer to after autoprobe in initf_dm() since the
trace test does not tolerate any variance.

This reverts commit 21dd873572.
