of: make of_find_device_by_node generic
There's no need for this function to be architecture specific and all four architectures defining it had the same definition. The function has been moved to drivers/of/platform.c. Signed-off-by: Jonas Bonn <jonas@southpole.se> [grant.likely@secretlab.ca: moved to drivers/of/platform.c, simplified code, and added kerneldoc comment] Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
