ENGR00231773-6 SDMA: add event pending trigger interface

When SDMA is use for periphal data transfer, dma request is trigger by
FIFO level. If the SDMA is started after the start of periphal, SDMA
would miss the first pulse and be not able to trigger itself.

In this patch, add interface to trigger a dma request manully.
