of: property: fw_devlink: Ignore interrupts property for some configs
When CONFIG_OF_IRQ is not defined, it doesn't make sense to parse interrupts property. Also, parsing and tracking interrupts property breaks some PPC devices[1]. But none of the IRQ drivers in PPC seem ready to be converted to a proper platform (or any bus) driver. So, there's not much of a point in tracking the interrupts property for CONFIG_PPC. So, let's stop parsing interrupts for CONFIG_PPC.
