SYV682x: Fix Source OCP for SYV682B revision
Force the EC to wait at least 15ms before checking to see if the alerts
are cleared.
This will fix source OCP for the SYV682B, which added a 10ms HW deglitch
to the source OC alert.
BUG=b:183761055
TEST=Check that OCP is triggered instead of TSD when the port is
overloaded on SYV682B
TEST=Check that the SYV682A OCP still works with 100ms deglitch
TEST=make buildall
BRANCH=None
