This dma engine driver directly accesses page_link assuming knowledge
that should be contained only in scatterlist.h.We replace this access with a call to sg_chain which is equivalent.

The ste_dma40 has burst level granularity on the residue
registers, which is necessary for some clients to know,
notably the UART. Before this patch we get this message:uart-pl011 80007000.uart: RX DMA disabled - no residue processing
This patch fixes it.

Since the introduction of the .directions flags, ste_dma40 was
never patched to indicate which transfer directions it can manage.
This causes a problem when trying to use the dmaengine for generic
ALSA SoC DMA:ux500-msp-i2s.1: Failed to get DMA channel capabilities, falling
back to period counting: -6This patch fixes this issue by indicating the supported transfer
directions for slave and memcpy channels.Signed-off-by: Linus Walleij
