KVM: arm64: Make TCR2_EL1 save/restore dependent on the VM features
As for other registers, save/restore of TCR2_EL1 should be gated
on the feature being actually present.
In the case of a nVHE hypervisor, it is perfectly fine to leave
the host value in the register, as HCRX_EL2.TCREn==0 imposes that
TCR2_EL1 is treated as 0.
