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.
It is, but its needed for 3f42b142ea11 ("serial: max310x: fix IO data
corruption in batched operations") which uses this new functionality.
