  It seems a bit unnecessary for the PLPKS code to have a user-visible
config option when it doesn't do anything on its own, and there's existing
options for enabling Secure Boot-related features.

It should be enabled by PPC_SECURE_BOOT, which will eventually be what
uses PLPKS to populate keyrings.

However, we can't get of the separate option completely, because it will
also be used for SED Opal purposes.

Change PSERIES_PLPKS into a hidden option, which is selected by
PPC_SECURE_BOOT.
