Subject: net: mvneta: add configuration for MBUS windows access protection

commit db6ba9a5371f173489df126739d0a1c2a50f347b upstream.

This commit adds missing configuration of MBUS windows access protection
in mvneta_conf_mbus_windows function - a dedicated variable for that
purpose remained there unused since v3.8 initial mvneta support. Because
of that the register contents were inherited from the bootloader.
