atpic: make sure atpic_init is called after IO APIC initialization

Browse Source 
After r269510 the IO APIC and ATPIC initialization is done at the same
order, which means atpic_init can be called before the IO APIC has
been initalized. In that case the ATPIC will take over the interrupt
sources, preventing the IO APIC from registering them.
