common: Move autoprobe out to board init
Rather than doing autoprobe within the driver model code, move it out to
the board-init code. This makes it clear that it is a separate step from
binding devices.
For now this is always done twice, before and after relocation, but we
should discuss whether it might be possible to drop the post-relocation
probe.
For boards with SPL, the autoprobe is still done there as well.
Note that with this change, autoprobe happens after the
EVT_DM_POST_INIT_R/F events are sent, rather than before.
