There's quite a few instances of board-specific code doing

off = fdt_path_offset(gd->fdt_blob, ...); ... ret = uclass_get_device_by_of_offset(..., off, &dev);

looking for an eeprom or a pmic via some alias. Such code can be simplified a little if we have a helper for directly getting a device via device tree path (including being given as an alias).

Implement it in terms of ofnode rather than raw offsets so that this will work whether live tree is enabled or not.

Looks fine but please add a test to ofnode.c
