[PATCH V3] arm: kirkwood: add dreamplug support.

[linux_arm@lakedaemon.net (Jason Cooper)]

Copied guruplug-setup.c and did s/guruplug/dreamplug/g.  Then, switched
to SPI based NOR flash.

Signed-off-by: Jason Cooper <linux_arm@lakedaemon.net>

Changes from v1

   - attempting dts, looking for pointers.

Changes from v2

   - resubmit as MACH_TYPE_DREAMPLUG (3550) is in arm/for-next, rebased
     against same.
   - removed lame fdt attempt, others are working on kirkwood fdt.  Will
     convert once kirkwood fdt is mainline.
   - s/boot_params/atag_offset/
   - added kirkwood_reset
   - 1 checkpatch.pl warning (help in Kconfig), looks the same as all
     other kirkwood boards...
