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.

It has been decided to use marvell, not mrvl, in the compatibility
property. Search & replace.

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.

Also, use inclusive register size for uart0.

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.
