Subject: [PATCH 5.4 18/92] net: mvpp2: Fix GoP port 3 Networking Complex Control configurations

From: Stefan Chulski <stefanc@...vell.com>

[ Upstream commit 2575bc1aa9d52a62342b57a0b7d0a12146cf6aed ]

During GoP port 2 Networking Complex Control mode of operation configurations,
also GoP port 3 mode of operation was wrongly set.
Patch removes these configurations.
