Currently the regmap_config structure only allows the user to implement single element register read/write using .reg_read/.reg_write callbacks. The regmap_bus already implements bulk counterparts of both, and is being misused as a workaround for the missing bulk read/write callbacks in regmap_config by a couple of drivers. To stop this misuse, add the bulk read/write callbacks to regmap_config and call them from the regmap core code.

This fairly clearly new functionality.
