Add support for the Versatile Express SYS_CFG registers, which provide a generic means of reading or writing configuration information from various parts of the board. We only implement shutdown and reset. Also make the RESETCTL register RAZ/WI on Versatile Express rather than reset the board. Other system registers are generally the same as Versatile and Realview. This includes a VMState version number bump for arm_sysctl, since we have new register state to preserve. It also adds sys_mci to the VMState while we're bumping the version number (an accidental omission from commit b50ff6f5).
