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!

Antoine
