Subject: [PATCH v5 5/7] ARM: kirkwood: convert to DT irqchip and clocksource
With recent support for true irqchip and clocksource drivers for Orion
SoCs, now make use of it on DT enabled Kirkwood boards.
This also introduces a new Kconfig option for legacy (non-DT) Kirkwood
where old code is moved out to and polishes DT board file a little bit.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@...il.com>

Changelog:
v4->v5:
- do not re-introduce already removed init_dma_coherent_pool_size
(Reported by Jason Cooper)
@Jason: I did a 'git grep init_dma_coherent_pool_size' and now there
are no users of that function - as it was before. Patch 6/7 only differs
in the 'index' diff line because of the rebase here. I will not resend that,
it should still apply.
