KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_VFIO capability number

This adds a capability number for in-kernel support for VFIO on
SPAPR platform.

The capability will tell the user space whether in-kernel handlers of
H_PUT_TCE can handle VFIO-targeted requests or not. If not, the user space
must not attempt allocating a TCE table in the host kernel via
the KVM_CREATE_SPAPR_TCE KVM ioctl because in that case TCE requests
will not be passed to the user space which is desired action in
the situation like that.
