dm: core: Add a function to bind child devices
We currently use dm_scan_fdt_node() to bind devices. It is an internal
function and it requires the caller to know whether we are pre- or post-
relocation.
This requirement has become quite common in drivers, so the current function
is not ideal.
Add a new function with fewer arguments, that does not require internal
headers. This can be used directly as a post_bind() method if needed.
