For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.

We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
  to be probed and failed
- fail the ->probe() of i2c-multi-instantiate

Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.
