x86: move ioapic code where it belongs
The commit 399287229c775a8962a852a761d65dc9475dec7c hacked the ioapic resource mapping into apic.c for no good reason. Move the code into io_apic_64.c where it belongs. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
