dm: sf: Add support for all targets which requires MANUAL_RELOC
It is follow up patch based on
"dm: Add support for all targets which requires MANUAL_RELOC"
(sha1: 484fdf5ba058b07be5ca82763aa2b72063540ef3)
to update function pointers for DM.
Using post_bind is not ideal but it is one on current option what can be
used. Variable reloc_done has to be used do not call relocation after
every bind. Maybe new core functions should be introduced for this case.
