x86/apic: Simplify init_bsp_APIC() usage
Since CONFIG_X86_64 selects CONFIG_X86_LOCAL_APIC, the following
condition:
#if defined(CONFIG_X86_64) || defined(CONFIG_X86_LOCAL_APIC)
is equivalent to:
#if defined(CONFIG_X86_LOCAL_APIC)
... and we can eliminate that #ifdef by providing an empty
init_bsp_APIC() stub in the !CONFIG_X86_LOCAL_APIC case.
Also add some comments to explain why we call init_bsp_APIC().
