Subject: [PATCH] pinctrl: hide subsystem from the populace

From: Linus Walleij <linus.walleij@...aro.org>

Machines that have embedded pin controllers need to select them
explicitly, so why broadcast their config options to menuconfig.
We provide a helpful submenu for those machines that do select
it, making it possible to enable debugging for example.
