Subject: net: phy: add __set_linkmode_max_speed
Patch-mainline: v5.4-rc1
Git-commit: 7b261e0ef5f88087765df7f079a4bd0d285f7579
References: bsc#1176447

We will need the functionality of __set_linkmode_max_speed also for
linkmode bitmaps other than phydev->supported. Therefore split it.

v2:
- remove unused parameter from __set_linkmode_max_speed
