KVM: arm64: vgic-v5: Move PPI caps into kvm_vgic_global_state

Browse Source 
Constant vgic properties are usually kept in kvm_vgic_global_state,
but the vgic-v5 code does its own thing.

Move the ppi_caps data into the global structure, which has the
modest additional advantage of making it ro_after_init.
