net: atlantic: MACSec offload skeleton

This patch adds basic functionality for MACSec offloading for Atlantic
NICs.

MACSec offloading functionality is enabled if network card has
appropriate FW that has MACSec offloading enabled in config.

Actual functionality (ingress, egress, etc) will be added in follow-up
patches.

Here is a bunch of atlantic driver new features and updates.

Shortlist:
- Me adding ethtool private flags for various loopback test modes,
- Nikita is doing some work here on power management, implementing new PM API,
He also did some checkpatch style cleanup of older driver parts.
- I'm also adding a new UDP GSO offload support and flags for loopback activation

Merge branch 'net-aquantia-PTP-support-for-AQC-devices'

Igor Russkikh says:

====================
net: aquantia: PTP support for AQC devices

This patchset introduces PTP feature support in Aquantia AQC atlantic driver.

This implementation is a joined effort of aquantia developers:
Egor is the main designer and driver/firmware architect on PTP,
Sergey and Dmitry are included as co-developers.
Dmitry also helped me in the overall patchset preparations.

Feature was verified on AQC hardware with testptp tool, linuxptp,
gptp and with Motu hardware unit.

version3 updates:
- Review comments applied: error handling, various fixes

version2 updates:
- Fixing issues from Andrew's review: replacing self with
ptp var name, making ptp_clk_offset a field in the ptp instance.
devm_kzalloc advice is actually non applicable, because ptp object gets
created/destroyed on each network device close/open and it should not be
linked with dev lifecycle.
- Rearranging commit authorship, adding Egor as a ptp module main maintainer
- Fixing kbuild 32bit division issues

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.
