Subject: x86: fix wakeup_cpu with numaq/es7000, v2, fix

Impact: fix wakeup_secondary_cpu with hotplug

We can not put that into x86_quirks, because that is __initdata.
So try to move that to genapic, and add update_genapic in x86_quirks.

later we even could use that stub to:

 1. autodetect CONFIG_ES7000_CLUSTERED_APIC
 2. more correct inquire_remote_apic with apic_verbosity setting.
