config: armv7hl/default: Disable DMA for MUSB
    
    Hi, this is both for stable and master.
    
    An issue is the following. We can not have multiple DMA modes in the same kernel due to current musb design.
    So, it will work only for specific hardware (OMAP DMA). Current configuration leads to OOPS at BeaglBone Black (CPI41 DMA which is disabled), because it tries to use wrong DMA functions (from OMAP DMA).
    
    The fairest way to fix it is to disable DMA for all hardware until fix in upstream.
