KVM: arm64: nv: Add missing EL2->EL1 mappings in get_el2_to_el1_mapping()
As KVM has grown a bunch of new system register for NV, it appears
that we are missing them in the get_el2_to_el1_mapping() list.
Most of them are not crucial as they don't tend to be accessed via
vcpu_read_sys_reg() and vcpu_write_sys_reg().
