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:

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.
