To support efforts to generalize handling of writable System ID Registers [1] this series addresses the demuxed registers that are kept outside of ARMISARegisters namely CSSELR_EL1.
CSSELR_EL1 is moved within ARMISARegisters and accessors to retrieve and set the demuxed values are provided. Initial values are gathered via the usual KVM_GET_ONE_REG ioctl.
