x86, apic: Use logical flat on intel with <= 8 logical cpus
On Intel platforms, we can use logical flat mode if there are <= 8
logical cpu's (irrespective of physical apic id values). This will
enable simplified and efficient IPI and device interrupt routing on
such platforms.
Fix the relevant comments while we are at it.
We can clean up default_setup_apic_routing() by using apic->probe()
but that is a different item.
