Hmm. So presumably Windows doesn't even do them bit-by-bit, but simply
does a "restore PM1 Control register value" on resume.
And I guess it probably does the same for the PM1_ENABLE register and the
PM2 control registers too?
Just restoring the whole register values _does_ sound a lot simpler than
worrying about individual bits.
