x86, ioapic: Use proper defines for the entry fields
While looking at the printout issue, I stumbled more than once over
the various 0/1 assignments which are either commented in strange ways
or force to lookup the meaning.
Use proper constants and fix the misleading comments. While at it
remove pointless 0 assignments in native_disable_io_apic() which have
no value for understanding the code.
