x86: Allow platforms to force enable apic
Some embedded x86 platforms don't setup the APIC in the BIOS/bootloader and would be forced to add "lapic" on the kernel command line. That's a bit akward. Split out the force enable code from detect_init_APIC() and allow platform code to call it from the platform setup. That avoids the command line parameter and possible replication of the MSR dance in the force enable code.
