powerpc/powernv: Call OPAL sync before kexec'ing Its possible that OPAL may be writing to host memory during kexec (like dump retrieve scenario). In this situation we might end up corrupting host memory. This patch makes OPAL sync call to make sure OPAL stops writing to host memory before kexec'ing.
