[v4,0/4] gpio: rockchip: Update the GPIO driver

Message

GPIO driver support acpi and new version, set input direction in
irq_request_resources, fix division error and debounce config error.

Changes since v1:
- Split commits with multiple changes into separate commits.
- Adjust backportable fix to the forefront.
- Modify messages of some commits.

Changes since v2:
- Optimize version number comments.
- Modify the GPIO version judgment logic.
- Use devm_clk_get_enabled to simplify the code.
- Use guard instead of mutex_lock to simplify the code.
- Use irq_hw_number_t and irqd_to_hwirq() in the request irq function.
- Since list_first_entry cannot return NULL, remove the NULL check.
- Temporarily do not add support for ACPI.

Changes since v3:
- Give up modifying the debounce config because it is not actually used.
- Do not add support for retrieving clocks using 'clock-names'.
