I'm already on the signed-off-by (mostly because I tweaked the commit
message and tested this), but in case anyone cares I have reviewed
this and tested it.  ;)

all of these clocks, but since we _just_ removed the blanket "leave
all clocks enabled" adding a few clocks back into the fold seems sane
until we get all our ducks in a row.
