sh: Kill off legacy UBC wakeup cruft.
This code was added for some ancient SH-4 solution engines with peculiar boot ROMs that did silly things to the UBC MSTP bits. None of these have been in the wild for years, and these days the clock framework wraps up the MSTP bits, meaning that the UBC code is one of the few interfaces that is stomping MSTP bits underneath the clock framework. At this point the risks far outweigh any benefit this code provided, so just kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
