Place IRQ handlers such as gic_handle_irq() in the irqentry section even
if FUNCTION_GRAPH_TRACER is not enabled. Without this, the stack
depot's filter_irq_stacks() does not correctly filter out IRQ stacks in
those configurations, which hampers deduplication and eventually leads
to "Stack depot reached limit capacity" splats with KASAN.
A similar fix was done for arm64 in commit f6794950f0e5ba37e3bbed
("arm64: set __exception_irq_entry with __irq_entry as a default").
