soc/intel/fsp_baytrail: set up for including irqroute.h twice

irq_helper.h intentionally gets included into irqroute.asl twice - once
for pic mode and once for apic mode.  Since people are used to seeing
guard statements on the .h files, add the guards to irqroute.h and add
a comment to irq_helper.h explaining why they aren't there.  Add a
time.
