Frank Li 796bdb33e8 dmaengine: Add API to combine configuration and preparation (sg and single) ... Previously, configuration and preparation required two separate calls. This works well when configuration is done only once during initialization. However, in cases where the burst length or source/destination address must be adjusted for each transfer, calling two functions is verbose and requires additional locking to ensure both steps complete atomically. Add a new API dmaengine_prep_config_single() and dmaengine_prep_config_sg() and callback device_prep_config_sg() that combines configuration and preparation into a single operation. If the configuration argument is passed as NULL, fall back to the existing implementation.
