mm: cma_alloc: allow to specify GFP mask
Most users of this interface just want to use it with the default
GFP_KERNEL flags, but for cases where DMA memory is allocated it may be
called from a different context.
No functional change yet, just passing through the flag to the
underlying alloc_contig_range function.
