regmap: split up regmap_config.use_single_rw
Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.
