Devicetree fixes for v5.15, take 2:

Browse Source 
- Revert fw_devlink tracking 'phy-handle' links. This broke at least a
   few platforms. A better solution is being worked on.
 
 - Add Samsung UFS binding which fell thru the cracks
 
 - Doc reference fixes from Mauro
 
 - Fix for restricted DMA error handling
