net: microchip: lan743x: add support for PTP pulse width (duty cycle)
If the PTP_PEROUT_DUTY_CYCLE flag is set, then check if the
request_on value in ptp_perout_request matches the pre-defined
values or a toggle option.
Return a failure if the value is not supported.
Preserve the old behaviors if the PTP_PEROUT_DUTY_CYCLE flag is not
set.
Tested with an oscilloscope on EVB-LAN7430:
e.g., to output PPS 1sec period 500mS on (high) to GPIO 2.
./testptp -L 2,2
./testptp -p 1000000000 -w 500000000
