pinctrl: Kconfig: sort pinctrl config options to prevent future clutter

This originally started out as
     "pinctrl: Kconfig: reorder to keep Rockchip options together"
and tried to keep the Rockchip-related config options together.

However, we now rewrite all chip-specific driver selections to start
with CONFIG_PINCTRL_ (with the inadvertent changes to related
Makefiles) and sort those alphabetically. And as this already means
touching most of the file, we also reformat the help text to not exceed
80 characters (but make full use of those 80 characters).
