Jean-Philippe Brucker 235aeafb93 arm64: Save and restore OSDLR_EL1 across suspend/resume
commit 827a108e354db633698f0b4a10c1ffd2b1f8d1d0 upstream.

When the CPU comes out of suspend, the firmware may have modified the OS
Double Lock Register. Save it in an unused slot of cpu_suspend_ctx, and
restore it on resume.
