target-arm: Use the right MMU index in arm_regime_using_lpae_format
arm_regime_using_lpae_format checks whether the LPAE extension is used for stage 1 translation regimes. MMU indexes not exclusively of a stage 1 regime won't work with this method. In case of ARMMMUIdx_S12NSE0 or ARMMMUIdx_S12NSE1, offset these values by ARMMMUIdx_S1NSE0 to get the right index indicating a stage 1 translation regime. Rename also the function to arm_s1_regime_using_lpae_format and update the comments to reflect the change.
