OpenWrt's developer guide prefers having actual patches so they an be
sent upstream more easily.
However, in the case of hack-5.15 patches which are not meant for
upstream, adding proper fields allows for `git am` to properly function.
This commit tries to rectify that, by digging in the history to find
where and how it was first added.

It isn't feasible to literally backport all upstream phylink_pcs changes
down to Linux 5.15: It's just too many patches, and many downstream
drivers and hacks are likely to break. We are too close to branching off
to risk this, and it's also just too much work.
Instead just add helper functions used by modern PCS drivers while keeping
the original functions instact as well. While this may add a kilobyte or
two of extra kernel size, it has the advantage that we get the best of both
worlds: None of the existing codepaths are touched, but yet we have the
option to backport singular improvements to Ethernet drivers where needed.
