rk3328_pin_ctrl uses type of RK3288 which has a hack in
rockchip_pinctrl_suspend and rockchip_pinctrl_resume to restore GPIO6-C6
at assume, the hack is not applicable to RK3328 as GPIO6 is not even
exist in it. So use a dedicated pinctrl type to skip this hack.

RV1126 has five GPIOs groups - GPIO0 in PD_MMU and GPIO1-4
in PD_BUS.
In GPIO0, up to Lower C group GPIO0_C[3:0] is part of PMU
but rest of the groups from there are part of GRF.
Added pinctrl support for RV1126 and the pull, drv and schmitt
calculations are inferred from [1] authored by Jianqun Xu.

Add pinctrl support for RK3588.
[merged in downstream fixes, simplified register lookup logic for better
maintanence at the cost of a bit more static const memory and fixed some
incorrect registers]

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.

The separation of pinctrl and gpio drivers created a tiny window where
a pinconfig setting might produce a null-pointer dereference.
The affected device were rk3288-veyron devices in this case.
Pinctrl-hogs are claimed when the pinctrl driver is registered,
at which point their pinconfig settings will be applied.
At this time the now separate gpio devices will not have been created
yet and the matching driver won't have probed yet, making the gpio->foo()
call run into a null-ptr.
As probing is not really guaranteed to have been completed at a specific
time, introduce a queue that can hold the output settings until the gpio
driver has probed and will (in a separate patch) fetch the elements
of the list.
We expect the gpio driver to empty the list, but will nevertheless empty
it ourself on remove if that didn't happen.
