KVM: arm64: Honor trap routing for TCR2_EL1
TCR2_EL1 handling is missing the handling of its trap configuration:
- HCRX_EL2.TCR2En must be handled in conjunction with HCR_EL2.{TVM,TRVM}
- HFG{R,W}TR_EL2.TCR_EL1 does apply to TCR2_EL1 as well
Without these two controls being implemented, it is impossible to
correctly route TCR2_EL1 traps.
