x86: Always use x86_cpu_to_logical_apicid for cpu -> logical apic id
Currently, cpu -> logical apic id translation is done by
apic->cpu_to_logical_apicid() callback which may or may not use
x86_cpu_to_logical_apicid. This is unnecessary as it should
always equal logical_smp_processor_id() which is known early
during CPU bring up.
Initialize x86_cpu_to_logical_apicid after apic->init_apic_ldr()
in setup_local_APIC() and always use x86_cpu_to_logical_apicid
for cpu -> logical apic id mapping.
