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.

Spaces are used for indentation in the definitions of all other
constants in this driver, so I think you should stick with this
convention, at least to remain consistent.
