0aa5369fdb pinctrl: realtek: Fix some NULL dereference warnings
Just inspecting the code doesn't convince me that this is a real
issue, but the tools complain that it is so I will just handle it.

d48f8a6f4a pinctrl: realtek: Tag unused pins as __maybe_unused
These pin definitions are helpful to have when working with the
driver in the future, so they are in a sense a bit like
documentation. They could be commented out as well, but why.

This should fix these build warnings:

8c58f51ff3 pinctrl: realtek: Fix error handling in probe()
There are several issues in the probe function:
1) of_iomap() return NULL on error but the code checks for error
   pointers.
2) pinctrl_register() is the reverse.  It returns error pointers
   but the code checks for NULL.
3) The error paths need to call iounmap(data->base) before returning
   to avoid a resource leak.

e99ce78030 pinctrl: realtek: Add common pinctrl driver for Realtek DHC RTD SoCs
The RTD SoCs share a similar design for pinmux and pinconfig.
This common pinctrl driver supports different variants within the RTD
SoCs.
