Without the clock being held by a driver, it gets turned off at a bad
time causing the SoC to lockup. This is often during reboot.

Select the generic mvebu kirkwood pincltr driver and generic mvebu
gpio driver. This requires minor changes to the DT, and the calls to
configure plat-orion gpio driver are removed.

Now that the EHCI driver has DT support, drop old style configuration
of it and add DT in its place. Since all the boards enable the EHCI,
enable it by default in kirkwood.dtsi. Any new boards which don't have
USB can specifically disable it.

With true DT clock providers available switch Kirkwood clock setup in
DT- enabled boards. While AUXDATA can be removed completely from bus
probing, some devices still don't know about DT. Therefore, some clkdev
aliases are created until these devices also move to DT.

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.

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.
