Title:
  arm emulation of HCR.TID3 traps are not implemented

Status in QEMU:
  Fix Committed

Bug description:
  On ARM (aarch64), HCR_EL2.TID3 [bit18] is supposed to trap ID group 3,
  which includes the ID_AA64{PFR,DFR,ISAR,MMFR,AFR}*_EL1 registers.
  However, setting that HCR bit has no effect and accesses to those ID
  registers are not trapped to EL2 with an EC syndrome value of 0x18.
