gpio/pinctrl-rockchip: Fixes for the recently separated gpio/pinctrl driver

A patchset in state Mainline for linux-kernel

It looks like rk3288-veyron(-pinky) was the one device in my boardfarm I didn't test the pinctrl/gpio patches on and it seems this one uses some specific parts none of the other do. So when I did my v5.15-rc1 testrun I got a surprise. Not only did the pinctrl-hogs cause a null-pointer exception but the device also entered a reset loop a bit later in the boot. This series addresses the issues in hopefully a nice way and should ideally become part of 5.15 before other people run into issues. * Patch 1 addresses the reset-loop, which is caused by a not-ideal check vor v1 vs. v2 controller in the debounce code * Patch 2 is just a find when looking through the code * Patches 3+4 address the pinctrl-hogs issue by creating a deferred queue where the pinctrl can temporarily store these hog settings if needed and the pinctrl driver can retrieve them during probe.
