test: regmap: test Linux-compatible syscon_node_to_regmap()
Like Linux, syscon_node_to_regmap() allows a node to work as a syscon provider without binding it to a syscon driver. Test this. Requested-by: Simon Glass <sjg@chromium.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
