[Skiboot] [PATCH v5 03/20] include/secvar.h: add .lockdown() hook to secvar storage driver

[Eric Richter]

Previously, it was implied that the storage driver would lock itself after
performing a write action. As this behavior is not particularly clear when
reviewing the main secvar flow, this action instead has been made explicit.
