Moving to the Device Tree implies having CONFIG_MULTI_IRQ_HANDLER
enabled, even for non-DT platforms (if we want both DT and non-DT
platforms to be supported in a single kernel).
However, the common CONFIG_MULTI_IRQ_HANDLER handler for non-DT
platforms in plat-orion/irq.c doesn't match the needs of
Orion5x. Also, it doesn't make much sense for orion_irq_init() to
register the multi-IRQ handler: orion_irq_init() is called once for
each IRQ cause/mask tuple, while the multi-IRQ handler only needs to
be registered once.
To solve this problem, we move the multi-IRQ handle in per-platform
code: mach-kirkwood/irq.c and mach-dove/irq.c. The Orion5x variant
will be introduced in a followup commit. Of course, this code will
ultimately be completely removed once all boards are converted to the
Device Tree.
