Pass the CPU index as a parameter to startup.
This addition is in support of future multicore support in coreboot. It also will allow us to remove some asssembly code. The CPU "index" -- i.e., its order in the sequence in which cores are brought up, NOT its APIC id -- is passed into the secondary start. We modify the function to specify regparm(0). We also take this opportunity to do some cleanup: indexes become unsigned ints, not unsigned longs, for example. Build and boot on a multicore system, with pcserial enabled. Capture the output. Observe that the messages Initializing CPU #0 Initializing CPU #1 Initializing CPU #2 Initializing CPU #3 appear exactly as they do prior to this change.
