generic: backport missing helper for phy interfaces

The function was defined before in the patch
"hack-5.15/795-backport-phylink_pcs-helpers.patch". However, the hack
did not move to 6.1. Instead of using the hack do the backport of
upstream accepted version.

Fixes errors in the form of:

Subject: [PATCH] net: phylink: add phylink_get_link_timer_ns() helper
Add a helper to convert the PHY interface mode to the required link
timer setting as stated by the appropriate standard. Inappropriate
interface modes return an error.
