[PATCH] mvebu: mark all mtd partitions on GL.iNet GL-MV1000 read-only

[Enrico Mioso]

On this device, two of the three defined MTD partitions arre
automatically set to read-only, since they do not end at an erase/write
block boundary.
In particular, the only partition remaining writable is the one holding
the u-boot bootloader.
Mark all of the partitions read-only, at least until a better
understanding of why the layout has been laid out this way is gained.
