Stijn Tintel 2c0cec1eb0 kernel: move mv88e6xxx fix to generic backports
The backports introduced in commit d40756563c ("kernel: backport
phylink changes from mainline Linux") broke the mv88e6xxx DSA driver.
A backport to fix this was added to the kirkwood target, but as it is
used in multiple targets, and there's a kmod package for it, the fix
should be in generic backports.

This fixes the switch on the WatchGuard Firebox M300 when running the
6.1 testing kernel.

There is no need to backport the fix for the 6.6 kernel, as it was
included in 6.6.5.

Subject: [PATCH 1/6] net: dsa: mv88e6xxx: pass directly chip structure to
mv88e6xxx_phy_is_internal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since this function is a simple helper, we do not need to pass a full
dsa_switch structure, we can directly pass the mv88e6xxx_chip structure.
Doing so will allow to share this function with any other function
not manipulating dsa_switch structure but needing info about number of
internal phys
