The Kirkwood-based PlatHome OpenBlocks A6 board has an Init button
connected to MPP pin 38. This commit adds support for this button.

Instead of having one separate pinmux configuration for each LED, for
each GPIO of the GPIO header, for each DIP switch, this patch groups
them together in configurations that make sense together: LEDs on one
side, GPIOs of the GPIO header on another side, and DIP switches on
yet another side.

When the pinmux mechanism was added in Kirkwood, the device driver
core was not yet providing the possibility of attaching pinmux
configurations to all devices, drivers had to do it explicitly, and
not all drivers were doing this.
Now that the driver core does that in a generic way, it makes sense to
attach the pinmux configuration to their corresponding devices.
This allows the pinctrl subsystem to show in debugfs to which device
is related which pins, for example:
pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41
pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42
pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43

When DT support for kirkwood was first introduced, there was no clock
infrastructure. As a result, we had to manually pass the
clock-frequency to the driver from the device node.
Unfortunately, on kirkwood, with minimal config or all module configs,
clock-frequency breaks booting because of_serial doesn't consume the
gate_clk when clock-frequency is defined.
The end result on kirkwood is that runit gets gated, and then the boot
fails when the kernel tries to write to the serial port.
Fix the issue by removing the clock-frequency parameter from all
kirkwood dts files.
Booted on dreamplug without earlyprintk and successfully logged in via
ttyS0.

OpenBlocks A6 has three leds via GPIO. This supports them.
And this fix typo about led, because hardware manual has typo.
