x86, irq, PCI: Keep IRQ assignment for runtime power management
Now IOAPIC driver dynamically allocates IRQ numbers for IOAPIC pins.
We need to keep IRQ assignment for PCI devices during runtime power
management, otherwise it may cause failure of device wakeups.
Commit 3eec595235c17a7 "x86, irq, PCI: Keep IRQ assignment for PCI
devices during suspend/hibernation" has fixed the issue for suspend/
hibernation, we also need the same fix for runtime device sleep too.
Fix: https://bugzilla.kernel.org/show_bug.cgi?id=83271
