powerpc/pseries: move the PLPKS config inside its own sysfs directory
The /sys/firmware/secvar/config directory represents Power LPAR Platform
KeyStore (PLPKS) configuration properties such as max_object_size, signed_
update_algorithms, supported_policies, total_size, used_space, and version.
These attributes describe the PLPKS, and not the secure boot variables
(secvars).
Create /sys/firmware/plpks directory and move the PLPKS config inside this
directory. For backwards compatibility, create a soft link from the secvar
sysfs directory to this config and emit a warning stating that the older
sysfs path has been deprecated. Separate out the plpks specific
documentation from secvar.
