Ah, I understand now how it's used from assembly code, but it took me a while
to figure out why it's done that way and that I couldn't come up with a better
solution either. Please add a comment above sirfsoc_rtciobrg_base and
sirfsoc_pwrc_base explaining that they are used from the suspend code and
that you don't need locking there.
