fdt: implement dev_get_addr_name()
This function parses the reg property based on an index found in the reg-names property. This is required for bindings that are written using reg-names rather than hard-coding indices in reg. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
