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.
