[Hafnium] Trapped access to system register and excpetion

Hello,

We get the following error in the non-secure terminal in the QEMU, while booting the normal world with hafnium(SPMC) at S-EL2 and SP at S-EL1. NOTICE: Trapped access to system register write: op0=1, op1=0, crn=7, crm=14, op2=2, rt=11. NOTICE: Injecting Unknown Reason exception into VM 0x8001.

Above system register found as DC CISW.

It found that this happened with the recent hafnium change "feat(interrupts): preferred managed exit signal" Thanks.
