net: aquantia: PTP skeleton declarations and callbacks Here we add basic function for PTP clock register/unregister. We also declare FW/HW capability bits used to control PTP feature on device. PTP device is created if network card has appropriate FW that has PTP enabled in config. HW supports timestamping for PTPv2 802.AS1 and PTPv2 IPv4 UDP packets. It also supports basic PTP callbacks for getting/setting time, adjusting frequency and time as well.

net: aquantia: add support for PIN funcs Depending on FW configuration we can manage from 0 to 3 PINs for periodic output and from 0 to 1 ext ts PIN for getting TS for external event. Ext TS PIN functionality is implemented via periodic timestamps polling directly from PHY, because right now there is now way to receive the PIN trigger interrupt from phy. The polling interval is 15 milliseconds.
