Subject: net/hns3: extract PTP to its own header file

[ upstream commit 8977e7539f40ac716138dd49456dc26bfbf439c5 ]

This patch extracts a PTP header file to contain PTP registers
and external API in order to make PTP code structure more clear.

Fixes: 38b539d96eb6 ("net/hns3: support IEEE 1588 PTP")
