Further data: the irq_domain_associate_many() calls that we're now doing
are also causing WARN_ON()s to go off during boot after commit 98aa46
(irqdomain: Support for static IRQ mapping and association) causing
breakage for my interrupt using MFDs.

I don't really have time to investigate now but backing out that commit
seems to make things much happier, I suspect there's some collision with
IRQs allocated statically by the platform but I don't immediately see
what's new here.
