    [ARM] Hide ISA DMA API when ISA_DMA_API is unset · dcea83ad
    Russell King authored
    When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
    so there's no point in publishing the prototypes via asm/dma.h, nor
    including the machine dependent parts of that API.
    
    This allows us to remove a lot of mach/dma.h files which don't contain
    any useful code.  Unfortunately though, some platforms put their own
    private non-ISA definitions into mach/dma.h, so we leave these behind
    and fix the appropriate #include statments.
