ptp: ocp: Add signal generators and update sysfs nodes
Newer firmware provides 4 programmable signal generators, add
support for those here. The signal generators provide the
ability to set the period, duty cycle, phase offset, and polarity,
with new values defaulting to prior values.
The period and phase offset are specified in nanoseconds.
E.g: period [duty [phase [polarity]]]
echo 500000000 > signal # 1/2 second period
echo 1000000 40 100 > signal # 1ms period, 40% on, offset 100ns
echo 0 > signal # turn off generator
