dm: core: Simplify dm_probe_devices()

Browse source 
There is no point in checking the pre_reloc flag, since devices not
marked as pre-reloc will not have been bound, so won't exist yet.

There doesn't seem to be any point in checking if the device has a
valid devicetree node either, so drop that too.
