[Skiboot] [PATCH v4 11/11] witherspoon: enable secvar for witherspoon platform

Secure variable support needs to be enabled for each platform, and each
platform needs to select which storage and backend drivers to use (or
alternatively implement their own). This patch adds secure variable
support to the witherspoon platform.
