[PATCH v1 1/5] dmaengine: arm-dma350: Fix source trigger bit

[Jelly Jia]

CH_CTRL_USESRCTRIGIN is the source trigger enable bit in CH_CTRL and
must use bit 25, not bit 26 which is the destination trigger enable bit
(CH_CTRL_USEDESTRIGIN).

The constant has no users yet, but enabling the source trigger input
would silently enable the destination trigger input instead, breaking
any transfer that waits for a peripheral request. Fix it before the
first user arrives.
