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.

Lots of code has now moved into the devicetree, leaving a collection of
useless header files. Tidy them up.

This applies cleanly atop of my previous patch, "[PATCH V2 2/2] ARM:
kirkwood: Use devicetree to define DNS-32[05] fan", which also removes
gpio-fan.h

Add support for the DNS-320 and DNS-325. Describe as much as currently possible
in the devicetree files, create a board-dnskw.c for everything else.

Changes since last submission (V3) [Addressing comments by]:-

* One MACH_DLINK_KIRKWOOD_DT for all dtb files [Grant Likely, Jason Cooper]
* Drop brain-dead select "select CONFIG_MTD_OF_PARTS" [Grant Likely]
* Don't add NAND support then throw it away immediately after [Grant Likely]
* Describe purpose of MPP 41, 42 & 49

Changes since last submission (V2):-

* Use IEEE-compliant "okay", rather than "ok" [Scott Wood]
