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.

Convert boards using DT, but the old way of configuring SATA to now
use properties in there DT file.

Add support for the IB-NAS6210 and IB-NAS 6220. Describe as much as
currently possible in the devicetree files, including the NAND partitions.
Use the partition scheme of the original firmware by default.
Create a board-ib62x0.c for everything else.
