[PATCH v2 4/5] ARM: dove: move DT boards to orion irqchip driver

[Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>]

With legacy devices mapping their irqs, we can now switch DT enabled
boards to orion irqchip driver.

Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

Changelog:
v1->v2:
- split off DT changes (Suggested by Jason Cooper)
- use irqchip_init (Suggested by Jason Gunthorpe)
