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).

Having some sort of ordering proofed helpful in a lot of other places
already. So for a larger number of rockchip socs it might be helpful
as well instead of an ever increasing unsorted list.

Rockchip socs are always named rkxxxx in all places, as also shown
by the naming of the rk3036 pinctrl file itself.
Therefore also name the config symbol according to this scheme.

The rk3288 pinctrl is very specific to this soc, so should
not hog the generic rockchip naming.

Add a simple driver which allows use of LEDs attached to GPIOs. The linux
device tree binding is used.

Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.

This implementation requires a driver for each type of LED (e.g GPIO, I2C).
