Josh Poimboeuf a9468df5ad x86/boot/64: Use a common function for starting CPUs 
There are two different pieces of code for starting a CPU: start_cpu0()
and the end of secondary_startup_64().  They're identical except for the
stack setup.  Combine the common parts into a shared start_cpu()
function.
