powerpc/pseries: define driver for Platform KeyStore
PowerVM provides an isolated Platform Keystore(PKS) storage allocation
for each LPAR with individually managed access controls to store
sensitive information securely. It provides a new set of hypervisor
calls for Linux kernel to access PKS storage.
Define POWER LPAR Platform KeyStore(PLPKS) driver using H_CALL interface
to access PKS storage.
