x86: remove update_apic from x86_quirks, fix

Browse source 
Impact: build fix

wakeup_secondary_cpu_via_init(), the default platform method for
booting a secondary CPU, is always used on UP due to probe_32.c,
if CONFIG_X86_LOCAL_APIC is enabled but SMP is off.

So provide a UP wrapper inline as well.
