Does the below patch work for you, it does two things:

1) Bump all Versatile IRQs to offset at 32, because it is using
  IRQ 0 which is NO_IRQ and illegal anyway so it's anyway
  a bug that should be fixed.

2) Make sure we call irq_create_mapping() if the start IRQ is
  anyway 0, as in the device tree case, and make sure to
  actually pass zero in that case.

In actual fact, only changing the offset to 32 is required to get
Versatile to boot with DT. That platform doesn't yet use vic_of_init().
It currently depends on pre-allocated irq_descs.

OK both are already upstream, because there was someone
else verifying they solved the problem.

And the second patch was needed on the Integrator which
does use SPARSE_IRQ + vic_init_of().
Probably the DT-based SPEArs need it too.
