Bring the ACPI path in sync with the device tree path and handle all the
IRQ fetching at probe time. This leaves the only IRQ handling at device
registration time being that which is passed directly through the board
info as either a resource or an actual IRQ number.

Changes since v4:
 - Pass acpi_device to i2c_acpi_get_irq
 - Pass the client acpi_device rather than the adaptor, I think (maybe
   hope is more accurate) this should fix the issue seen by Benjamin.

Thanks,
Charles
