KVM: PPC: Add hidden flag for paired singles

The Gekko implements an extension called paired singles. When the guest wants
to use that extension, we need to make sure we're not running the host FPU,
because all FPU instructions need to get emulated to accomodate for additional
operations that occur.

This patch adds an hflag to track if we're in paired single mode or not.
