Felix Held 98fb72fa3f cpu/x86/mp_init: don't wait between INIT and SIPI for X86_AMD_INIT_SIPI 
Since current AMD SoCs don't need some wait time between INIT and SIPI,
we can skip the 10ms wait there, which improves the boot time a bit.

before: CPU_CLUSTER: 0 init finished in 632 msecs
after:  CPU_CLUSTER: 0 init finished in 619 msecs

mpinit still works on Mandolin and all CPU cores show up and are usable.
This also doesn't change the binary in a timeless build for boards/SoCs
that don't select X86_AMD_INIT_SIPI which I verified for lenovo/x230.
