powerpc/pseries: Query hypervisor for count cache flush settings

commit ba72dc171954b782a79d25e0f4b3ed91090c3b1e upstream.

Use the existing hypercall to determine the appropriate settings for
the count cache flush, and then call the generic powerpc code to set
it up based on the security feature flags.
