Subject: [PATCH 020/114] x86: clean up apic->apic_id_registered() methods
Impact: cleanup
x86 subarchitectures each defined a "apic_id_registered()" method,
which could be an inline function depending on which subarch we build
for, and which was also the name of a genapic field.
Untangle this namespace spaghetti by giving each of the instances
a separate name.
Also remove wrapper macro obfuscation.
