ef1683d5c3 x86: Pass correct cpu_index to ap_init() 
In sipi_vector.S, cpu_index (passed as %eax) is wrongly overwritten
by the ap_init() function address. Correct it.

45b5a37836 x86: Add multi-processor init 
Most modern x86 CPUs include more than one CPU core. The OS normally requires
that these 'Application Processors' (APs) be brought up by the boot loader.
Add the required support to U-Boot to init additional APs.
