ptp: Use ktime_get_clock_ts64() for timestamping
The inlined ptp_read_system_[pre|post]ts() switch cases expand to a copious
amount of text in drivers, e.g. ~500 bytes in e1000e. Adding auxiliary
clock support to the inlines would increase it further.
Replace the inline switch case with a call to ktime_get_clock_ts64(), which
reduces the code size in drivers and allows to access auxiliary clocks once
they are enabled in the IOCTL parameter filter.
No functional change.
