control:p10bmc: Update DVFS temp events

Update the initial delta from -3 to -10 degrees from the DVFS temp for
when to start increasing fans. Also update the parameter names to
denote that they are for fan target increases since a follow-on commit
will add actions to do something similar for fan target decreases using
a different delta from DVFS.
