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

In order to prepare the switch to the standard MMC device tree parser
for mvsdio, adapt all current uses of mvsdio in the dts files to the
standard format.

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.

Add a DT node for I2C and pinctrl hog for the pins. There appears to
be an i2c bus on topkick with a device on it:

i2cdetect 0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x03-0x77.

With the change to a DT based pinctrl/gpio driver, using gpio API
calls in board-*.c files no longer works, a dereferenced NULL pointer
exception occurs instead. By converting the GPIO code into a
fixed-regulator which gets probed later once pinctrl/gpio is
available, we avoid the exception.

This is a new kirkwood box made by Universal Scientific Industrial, Inc.
The product description is here:

http://www.usish.com/english/products_topkick1281p2.php

It is very similar to the dreamplug and other plug devices, with the
exception that it has room for a 2.5" SATA HDD internally.
