Andy Shevchenko 2692c614f8 device property: Allow secondary lookup in fwnode_get_next_child_node() 
When device_get_child_node_count() got split to the fwnode and device
respective APIs, the fwnode didn't inherit the ability to traverse over
the secondary fwnode. Hence any user, that switches from device to fwnode
API misses this feature. In particular, this was revealed by the commit
1490cbb9db ("device property: Split fwnode_get_child_node_count()")
that effectively broke the GPIO enumeration on Intel Galileo boards.
Fix this by moving the secondary lookup from device to fwnode API.

Note, in general no device_*() API should go into the depth of the fwnode
implementation.

Fixes: 114dbb4fa7 ("drivers property: When no children in primary, try secondary")
