    libpayload: mips: Use KSEG1 to access DMA-coherent memory
    
    Use bus_to_virt() to convert the physical address of the DMA
    coherent region to an address in KSEG1 which is suitable for
    device memory accesses.
    
    BUG=chrome-os-partner:36258
    BRANCH=none
    TEST=Build and boot on Pistachio.
