Subject: [PATCH 5.10 158/167] net: dsa: mv88e6xxx: enable SerDes PCS register dump via ethtool -d on Topaz

From: Marek Behún <kabel@...nel.org>

commit 953b0dcbe2e3f7bee98cc3bca2ec82c8298e9c16 upstream.

Commit bf3504cea7d7e ("net: dsa: mv88e6xxx: Add 6390 family PCS
registers to ethtool -d") added support for dumping SerDes PCS registers
via ethtool -d for Peridot.

The same implementation is also valid for Topaz, but was not
enabled at the time.
