    ramips: Improve Sanlinking D240 config
    
    * The left most mini-PCIe slot (the one attached to SIM2) can be
    power-cycled by setting GPIO 0 to high/low.
    
    * The D240 only needs the MT76x2 module, so update makefile to reflect this.
    Note that until the default mt7620 target is updated, then kmod-mt76 (and thus
    kmod-mt7603) will be selected by default.
    
    v2->v3:
    * Indentation error.
    
    v1->v2:
    * Rename gpio and remove redundant comment (thanks Piotr Dymacz)
