i386: select correct components for no-board build
The local APIC is a part of the CPU and has callbacks that are invoked
from multiple accelerators.
The IOAPIC on the other hand is optional, but ioapic_eoi_broadcast is
used by common x86 code to implement the IOAPIC's implicit EOI mode.
Add a stub in case the IOAPIC device is not included but the APIC is.
