KVM: SEV: Consolidate the SEV policy bits in a single header file
Consolidate SEV policy bit definitions into a single file. Use
include/linux/psp-sev.h to hold the definitions and remove the current
definitions from the arch/x86/kvm/svm/sev.c and arch/x86/include/svm.h
files.
No functional change intended.
