Merge branch 'fec-ptp'

Luwei Zhou says:

====================
Enable FEC pps feather

Change from v2 to v3:
	-Using the default channel 0 to be PPS channel not PTP_PIN_SET/GETFUNC interface.
	-Using the linux definition of NSEC_PER_SEC.

Change from v1 to v2:
	- Fix the potential 32-bit multiplication overflow issue.
	- Optimize the hareware adjustment code to improve efficiency as Richard suggested
	- Use ptp PTP_PIN_SET/GETFUNC interface to set PPS channel not device tree
	and add PTP_PF_PPS enumeration
	- Modify comments style
