Bumyong Lee 02b0538b99 dmaengine: pl330: issue_pending waits until WFP state 
[ Upstream commit 22a9d9585812440211b0b34a6bc02ade62314be4 ]

According to DMA-330 errata notice[1] 71930, DMAKILL
cannot clear internal signal, named pipeline_req_active.
it makes that pl330 would wait forever in WFP state
although dma already send dma request if pl330 gets
dma request before entering WFP state.

The errata suggests that polling until entering WFP state
as workaround and then peripherals allows to issue dma request.
