[PATCH 3.6.0] of: Add missing dummy functions

[Srinivas KANDAGATLA]

From: Srinivas Kandagatla <srinivas.kandagatla at st.com>

Some functions in of.h have dummy functions and real implementations,
however few of them have only real implementation.
I think to be more consistent this patch adds below dummy functions if
for non CONFIG_OF's.

	of_find_node_by_type
	of_device_is_available
	of_find_node_with_property
	of_find_matching_node
	of_find_node_by_path
	of_find_node_by_phandle
	of_get_parent
	of_get_next_parent
	of_get_next_child
	of_get_next_available_child
	of_get_child_by_name

Hopefully this can eliminate the need to ifdef code in the drivers.
