dmaengine: sprd: Support DMA link-list cyclic callback

Browse source

[ Upstream commit 97dbd6ea02 ]

The Spreadtrum DMA link-list mode is always one cyclic transfer,
so we should clear the SPRD_DMA_LLIST_END flag for the link-list
configuration. Moreover add cyclic callback support for the cyclic
transfer.
