    armv7: specify operational condition codes for msr instruction
    
    This adds condition codes when using the msr instruction. Although
    described as "optional" in the Cortex-A series programmer's guide,
    our experience with using the msr instruction in the payload suggests
    that the condition code is not optional and that this only worked
    in coreboot (and u-boot) because the processor comes up in SVC32 mode.
