x86: IO-APIC code has no dependency on PCI
The IRQ handling code requires pcidevs_lock to be held only for MSI
interrupts.
As the handling of which was now fully moved into msi.c (i.e. while
applying fine without, the patch needs to be applied after the one
titled "x86: split MSI IRQ chip"), io_apic.c now also doesn't need to
include PCI headers anymore.
