Subject: [PATCH net v2 1/2] net: mvpp2: Fix GoP port 3 Networking Complex Control configurations

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

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.
GENCONF_CTRL0_PORTX naming also fixed.

Fixes: f84bf386f395 ("net: mvpp2: initialize the GoP")
