regmap_init_i2c is quite limited right now and only supports 8-bit registers and values. In future, we may want to expand this further, but that would require us to format the regmap_config appropriately, pulling in more code that's not required in the general case, where reg_read and reg_write can be used directly. Add a new Kconfig symbol and select it where appropriate to allow us to split formatted regmap handling from the more basic handling we currently have. We intentionally don't provide a stub function, so out-of-tree users without the select fail to link and can be fixed.
