pinctrl/rockchip: support deferring other gpio params
Add support for deferring other params like PIN_CONFIG_INPUT_ENABLE.
This will be used to add support for PIN_CONFIG_INPUT_ENABLE to the
driver.
Fixes: e7165b1dff06 ("pinctrl/rockchip: add a queue for deferred pin output settings on probe")
Fixes: 59dd178e1d7c ("gpio/rockchip: fetch deferred output settings on probe")
