Add support for instantiating this driver from device tree, and add
the necassary DT information to the kirkwood.dtsi file.
This is based on previous work by Michael Walle and Jason Cooper.

The MV64XXX I2C driver needs a clock in order to calculate the baud
rate factors. So add an clk to the clk tree. Also add the base DT
properties for kirkwood devices.

Populate the devices with auxdata to set the device names which are used by
clkdev to lookup the clocks.

v2: Add interrupts properties, although not used.
Both IRQ and GPIO controllers can now be represented in DT. The IRQ
controllers are setup first, and then the GPIO controllers. Interrupts
for GPIO lines are placed directly after the main interrupts in the
interrupt space.

Add default configuration for NAND, to be enabled in your board config. Ensure
clock gating is set appropriately when the NAND is enabled.

Define both uarts in kirkwood.dtsi as they are common to all kirkwood
SoCs. Each board may enable all or none of them, so they are disabled
by default. uart0 is enabled for the dreamplug.
tclk can vary for each board, so we leave it undefined in the kirkwood
dtsi. Each board can then set it as appropriate when enabling the uart.

Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g.
Then, switched to SPI based NOR flash.
After talking to Arnd Bergman, chose an incremental approach to adding
devicetree support. First, we use the dtb to tell us we are on the
dreamplug, then we gradually port over drivers.
Driver porting will start with the uart (see next patch), and progress
from there. Possibly, spi/flash/partitions will be next.
When done, board-dt.c will no longer be dreamplug specific, and dt's can
be made for the other kirkwood boards.
