Add BD9574MWF support into bd9571mwv gpio, mfd and regulator drivers.
Latest Ebisu-4D boards has this chip instead of BD9571MWV so that
we need this patch series to detect this chip at runtime.
Note that the patch [1/12] is a bug-fix patch for mfd driver.
Changes from v3:
- Add "Acked-for-MFD-by" in patch 1, 3, 9 and 10.
- Use "Co-developed-by" instead in patch 11.
- In patch 11:
-- Remove abusing kernel-doc formatting in patch.
-- Rename bd957x_data with bd957x_ddata in patch.
-- Remove product name printk.
-- Rename bd9571mwv_identify() with bd957x_identify().
-- Remove argument "part_name" from bd957x_identify().
-- Modify dev_err() string.
-- Rename BD9571MWV_PRODUCT_CODE_VAL with BD9571MWV_PRODUCT_CODE_BD9571MWV.
-- Fix errno from -ENOENT to -ENODEV.
- In patch 12:
-- Rename "MFD driver" to "core driver".
-- Remove unnecessary comments.
-- Rename BD9574MWF_PRODUCT_CODE_VAL with BD9571MWV_PRODUCT_CODE_BD9574MWF.

Changes from v2:
- Use devm_mfd_add_devices() to remove the mfd device in unload.
- Update commit descriptions in patch 4 and 8.
- Use regmap_get_device() to simplify in patch 4.
- Remove "struct bd9571mwv" and bd9571mwv_remove().
- Add Reviewed-by in patch 3 to 9.
- Use devm_regmap_add_irq_chip() to simplify in patch 10.
https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=400477
Changes from v1:
- Document BD9574MWF on the dt-binding.
- Add ROHM_CHIP_TYPE_BD957[14] into rohm-generic.h.
- To simplify gpio and regulator drivers, using regmap instead of
using struct bd9571mwv.
- Remove BD9574MWF definitions to make gpio and regulator driver
simple to support for BD9574MWF.
- Add BD9574MWF support for gpio and regulator drivers.
- Add missing regmap ranges for BD9574MWF.
- Rename "part_number" with "part_name".
