add the undocumented CLK_* options to that section as well.

# CLOCK OPTIONS
# The granularity of operation is controlled by the kernel option HZ whose
# default value (100) means a granularity of 10ms. For an accurate simulation
# of high data rates it might be necessary to reduce the timer granularity to
# 1ms or less. Consider, however, that some interfaces using programmed I/O
# may require a considerable time to output packets. So, reducing the
# granularity too much might actually cause ticks to be missed thus reducing
# the accuracy of operation.
