net: stmmac: Add Flexible PPS support
This adds support for Flexible PPS output (which is equivalent
to per_out output of PTP subsystem).
Tested using an oscilloscope and the following commands:
1) Start PTP4L:
# ptp4l -A -4 -H -m -i eth0 &
2) Set Flexible PPS frequency:
# echo <idx> <ts> <tns> <ps> <pns> > /sys/class/ptp/ptpX/period
Where, ts/tns is start time and ps/pns is period time, and ptpX is ptp
of eth0.
