[PATCH v4 00/21] Add basic pinctrl drivers for JHB100 SoC

The JHB100 SoC has 13 pinctrl domains - sys0, sys0h, sys1, sys2, per0, per1,
per2, per2pok, per3, adc0, adc1, emmc, and vga.

In the current series, we will only add the following pinctrl:
 - sys0, sys0h, sys1, sys2
 - per0, per1, per2, per2pok, per3

The remaining pinctrl will be implemented in future series.

This series depends on the series:

Change since v3:

PATCH 3/5/7/9/11/13/15/17/19:
- Restrict input-debounce-ns to a maximum of 10,485,680.

PATCH 9/11/13/15/19/21:
- Change power-source to set the actual voltage in millivolts.

PATCH 19:
- Add support for an option to set 2500 mV.

PATCH 4:
- Use GPIO_GENERIC to register the GPIO controller.
- Acquire sfp->lock with raw_spinlock_irqsave guard.
- Implement the .gpio_request_enable and .gpio_set_direction
  callbacks for struct pinmux_ops。
- Add reset_control_assert on driver unload.
- Convert the pincfg structure to an enum array.
- Simplify the calculation of the number of GPIOs in a GPIO bank.
- Remove check_pinctrl_layouts() to improve code readability.

PATCH 4/6/8/10/12/14/16/18/20:
- Add const qualifiers to struct config_reg_layout_desc
  and struct starfive_pinctrl_regs.

v1: https://lore.kernel.org/all/[email protected]/
