Tom Lendacky 46d010e04a x86/boot/realmode: Check for memory encryption on the APs 
Add support to check if memory encryption is active in the kernel and that
it has been enabled on the AP. If memory encryption is active in the kernel
but has not been enabled on the AP, then set the memory encryption bit (bit
23) of MSR_K8_SYSCFG to enable memory encryption on that AP and allow the
AP to continue start up.
