[PATCH v7 0/9] gpio: realtek: Add support for Realtek DHC RTD1625

For better review flow, this series includes Andy Shevchenko's
gpio-regmap fix patches [1] as a prerequisite. The first patch
reverts the previously applied patch from Bartosz Golaszewski.

This series then adds GPIO support for the Realtek DHC RTD1625 SoC.

Unlike the existing driver (gpio-rtd.c) which uses shared bank
registers, the RTD1625 features a per-pin register architecture where
each GPIO line is managed by its own dedicated 32-bit control register.
This distinct hardware design requires a new, separate driver.

Patch 3:
- Add Reviewed-by tag from Michael.

Patch 4:
- Add Reviewed-by tag from Michael.
- Fix indentation by replacing spaces with a tab.

Patch 5 & 6:
- Create patch 6 and move value_xlate changes into patch 6.
- Add background context to kernel-doc comment for
'enum gpio_regmap_operation'.

Patch 7:
- Drop the reviewed by tag from Andy due to the signature changes.
- Add 'struct gpio_regmap' as the first parameter to the set_config callback.
- Add wrapper to bridge gpio_chip to gpio_regmap.

Patch 8:
- Add Reviewed-by tags from Michael and Andy.

Patch 9:
- Replace break with return 0 in functions that only consist of a switch-case
statement.
- Add a comment for 'platform_get_irq_optional()'.
- Update rtd1625_gpio_set_config() to align with the newly revised set_config
signature.
- Replace 'irq_domain_create_linear()' and 'devm_add_action_or_reset' with
