Finally you can move the OF dependency to the PINCTRL_BERLIN config as
all Berlin pinctrl drivers depends on it.

PINCTRL_BERLIN isn't user visible and it's selected by PINCTRL_BERLIN_BG4CT. So
we may have the following random config case:

CONFIG_OF=n
CONFIG_PINCTRL_BERLIN_BG4CT=y

In this case, there will be build errors for we missed OF. So we have to
make PINCTRL_BERLIN_BG4CT depends on OF. What do you think? Or is there
better solution?

That's true.

But because other Berlin pinctrl drivers also depends on CONFIG_OF, we
need to make then depend on it too. This isn't the topic of this series
so I'll send a separate patch later.
