Subject: [PATCH 4/5] x86, ioapic: Seperate print_IO_APIC() to only print one
 io apic


It is getting too big after interrupt remaping entries debug print out
was added.

Original print_IO_APIC become print_IO_APICs.
New print_IO_APIC will only print one ioapic registers

it will make checpatch.pl happy with removing indent warning..
