Let RPMH clients call rpmh_write_sleep_and_wake() to immediately
write cached sleep and wake data to the TCSes.

This patch doesn't hold weight on its own.  Please squash with patch
#3.  Specifically any clients actually trying to call this function
will hit the problems that patch #3 fixes.  There's no reason to add
broken code first and then fix it with a later patch in the same
series.
