Weidong, Can we also fix these config options?

Today, selecting CONFIG_INTR_REMAP automatically selects
CONFIG_X86_X2APIC. It should be the other way round.

i.e., turning on CONFIG_X86_X2APIC should automatically enable
CONFIG_INTR_REMAP and just enabling CONFIG_INTR_REMAP shouldn't enable
CONFIG_X86_X2APIC.

Also please make sure that the code compiles (and works :)) in different
combinations of these config settings.

thanks,
suresh
