of: Move definition of of_find_next_cache_node into common code.
Since the definition of_find_next_cache_node is architecture independent, the existing definition in powerpc can be moved to driver/of/base.c Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Grant Likely <grant.likely@linaro.org> Cc: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Sudeep KarkadaNagesha <sudeep.karkadanagesha@arm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
