sparc32: dma_alloc_coherent must honour gfp flags
dma_zalloc_coherent() calls dma_alloc_coherent(__GFP_ZERO) but the sparc32 implementations sbus_alloc_coherent() and pci32_alloc_coherent() doesn't take the gfp flags into account. Tested on the SPARC32/LEON GRETH Ethernet driver which fails due to dma_alloc_coherent(__GFP_ZERO) returns non zeroed pages.
