Now that all the device tree support is in mach-mvebu, remove it from
mach-kirkwood.

Regenerate kirkwood_defconfig, removing all DT support, and a couple

s/DT/board-file/?

We keep any system using -setup.c files, and remove the ability to
boot systems with a DT description. Thus mach-kirkwood becomes legacy,
and you should now be trying to only use mach-mvebu, compiled for v5
systems and a second compile for v7 systems.

There are four systems left in mach-kirkwood which don't have DT
equivalent. These are LaCie 2Big and 5Big, HP t5325 thin client and
Marvell OpenRD machines. I'm working on t5325 and Openrd. The sticking
point is audio support, which no other board has done with DT yet.
The two LeCie boards have a custom LED driver which needs a DT
binding. My gut feeling is that we won't get these four converted to
DT in time for 3.15.

Why not do like we did when we started the kirkwood dt conversion?
Create dts files for the remaining boards, and do

if (of_machine_is_compatible(...))
	legacy_audio_init()

in board-v5.c?

I suspect audio is going to take time to sort out.  I'd hate to delay
this just for that.

thx,

Jason.
