isapc: Remove unnecessary migration compatibility code 



We don't touch isapc when we change guest ABI and add new entries
to PC_COMPAT_* or new PCMachineClass compat flags.  This means
isapc never guaranteed guest ABI and cross-QEMU-version live
migration compatibility.  There's no point in keeping code for
kvm-pv-eoi and APIC ID compatibility in pc_init_isa().
