Marek Szyprowski d834c5ab83 kernel/dma: remove unsupported gfp_mask parameter from dma_alloc_from_contiguous() 
The CMA memory allocator doesn't support standard gfp flags for memory
allocation, so there is no point having it as a parameter for
dma_alloc_from_contiguous() function.  Replace it by a boolean no_warn
argument, which covers all the underlaying cma_alloc() function
supports.

This will help to avoid giving false feeling that this function supports
standard gfp flags and callers can pass __GFP_ZERO to get zeroed buffer,
what has already been an issue: see commit dd65a941f6 ("arm64:
dma-mapping: clear buffers allocated with FORCE_CONTIGUOUS flag").
