Robin Murphy e1bc5d1b8e arm64: Handle trapped DC CVAP ... Cache clean to PoP is subject to the same access controls as to PoC, so if we are trapping userspace cache maintenance with SCTLR_EL1.UCI, we need to be prepared to handle it. To avoid getting into complicated fights with binutils about ARMv8.2 options, we'll just cheat and use the raw SYS instruction rather than the 'proper' DC alias.
