Add the pin-controller driver for Marvell Berlin BG4CT SoC, with definition
of its groups and functions. This uses the core Berlin pinctrl driver.

This endif ends the following condition:

	if ARCH_BERLIN
	[...]

So the "depends on ARCH_BERLIN" here can be dropped. Also the
COMPILE_TEST can be moved as it isn't BG4CT specific and all other
Berlin pinctrl drivers would benefit from this.

So we would have something like:

	if (ARCH_BERLIN || COMPILE_TEST)
	[...]
	endif

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

Thanks!

Oh yeah! This is better.

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?

Thanks for kind review,
Jisheng

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.
