    dma_heap_allocation_data defines the UAPI as follows:
    
     struct dma_heap_allocation_data {
            __u64 len;
            __u32 fd;
            __u32 fd_flags;
            __u64 heap_flags;
     };
    
    But dma heaps are casting both fd_flags and heap_flags into
    unsigned long. This patch makes dma heaps - cma heap and
    system heap have consistent types with UAPI.
