dm: core: Move "/chosen" and "/firmware" node scan

Use the new function dm_scan_fdt_ofnode_path() to scan all the nodes
which aren't devices themselves but may contain some:
- "/chosen"
- "/clocks"
- "/firmware"

The patch removes the strcmp call in recursive function dm_scan_fdt_live()
and also corrects a conflict with the 2 applied patches in
the commit 1712ca21924b ("dm: core: Scan /firmware node by default")
and in the commit 747558d01457 ("dm: fdt: scan for devices under
/firmware too"): the subnodes of "/firmware" (optee for example)
are bound 2 times.

For example the dm tree command result on STM32MP1 is:

STM32MP> dm tree
 Class     Index  Probed  Driver                Name
 -----------------------------------------------------------

...
 tee           1  [   ]   optee                 `-- optee
