powerpc: Load firmware trusted keys/hashes into kernel keyring

The keys used to verify the Host OS kernel are managed by firmware as
secure variables. This patch loads the verification keys into the
.platform keyring and revocation hashes into .blacklist keyring. This
enables verification and loading of the kernels signed by the boot
time keys which are trusted by firmware.
