of/sparc: move is_root_node() to of.h
Rename is_root_node() to of_node_is_root() and make it available for all archs to use, as it's not PROM-specific. Signed-off-by: Andres Salomon <dilinger@queued.net> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
