KVM: arm64: Honor trap routing for TCR2_EL1

Browse source

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.
