Subject: dmaengine: zx: set DMA_CYCLIC cap_mask bit

From: Shawn Guo <shawn.guo@linaro.org>


[ Upstream commit fc318d64f3d91e15babac00e08354b1beb650b57 ]

The zx_dma driver supports cyclic transfer mode.  Let's set DMA_CYCLIC
cap_mask bit to make that clear, and avoid unnecessary failure when
clients request channel via dma_request_chan_by_mask() with DMA_CYCLIC
bit set in mask.
