    ARM: GIC: export and extend vgic_init_pending_irq()
    
    For LPIs we later want to dynamically allocate struct pending_irqs.
    So beside needing to initialize the struct from there we also need
    to clean it up and re-initialize it later on.
    Export vgic_init_pending_irq() and extend it to be reusable.
