regmap: Allow regmap_bulk_read() to work for "no-bus" regmaps
regmap_bulk_read() should decay to performing individual reads if we're using a "no-bus" regmap. Unfortunately, it returns an error because there is no map->bus pointer. Fix it. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Mark Brown <broonie@linaro.org>
