Subject: [PATCH 5.14 057/432] dmaengine: imx-sdma: remove duplicated sdma_load_context

From: Robin Gong <yibin.gong@....com>

commit e555a03b112838883fdd8185d613c35d043732f2 upstream.

Since sdma_transfer_init() will do sdma_load_context before any
sdma transfer, no need once more in sdma_config_channel().

Fixes: ad0d92d7ba6a ("dmaengine: imx-sdma: refine to load context only once")
