The purpose of the EVT14 handler may depend on whether CONFIG_IPIPE is enabled, albeit its implementation can be the same in both cases. When the interrupt pipeline is enabled, EVT14 can be used to raise the core priority level for the running code; when CONFIG_IPIPE is off, EVT14 can be used to lower this level before running softirq handlers. Rename evt14_softirq to evt_evt14 to pick an identifier that fits both, which allows to reuse the same vector setup code as well.
