    ARM: pci: mark pci_reserve_io as __init
    
    pci_reserve_io calls the vm_reserve_area_early function that is
    marked __init, so it needs to be __init itself to avoid this
    warning:
    
    WARNING: arch/arm/mm/built-in.o(.text+0x22dc): Section mismatch in
    reference from the function pci_reserve_io() to the function
    .init.text:vm_reserve_area_early()
