The default flags for freshly allocated interrupts are platform dependent, and apparently powerpc and arm set IRQ_NOREQUEST by default.
The normal path is to clear this flag from irq_domain_associate_locked(), which wraps the irq domain's "map" function, but the xe driver does not define an irq domain and instead allocates the irq descriptor directly, so the flags need to be set up manually as well.
