[RFC PATCH 39/77] check: Get 'chosen' node using get_subnode()

get_node_by_path() is going to be replaced by a more generic function in
order to handle orphan node support for addon device-tree.

The 'chosen' node is a subnode of the root node and can perfectly be
retrieved using get_subnode().

In preparation of the future change related to get_node_by_path(),
replace its usage to get the 'chosen' node by call to get_subnode().

The modification doesn't introduce any functional changes.
