armv7: specify condition code 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.
(credit to Gabe Black for finding this, I'm only uploading the patch)
