[RFC PATCH v2 43/74] dtc: Change fill_fullpaths() signature to take dt_info

[Herve Codina <herve.codina@bootlin.com>]

The future introduction of orphan nodes for addons device-tree will lead
to more than one tree in the addons data. Those trees will be:
  - the classical root tree starting at the root node
  - trees related to orphan nodes

Also, an addon device-tree can have only trees based on orphan nodes. In
other words an addon device-tree is valid without having the classical
'root' tree.

To prepare orphan nodes introduction, move fill_fullpaths() parameter
one level up and use dt_info struct instead of the 'root' tree (i.e.
dti->dt).

This change doesn't lead to any functional changes.
