DMAENGINE: Remove stedma40_set_psize and pre_transfer hook in ste_dma40
Remove obsolete pre_transfer hook in stedma40_chan_cfg. The intent of this hook is merely to handle burst size compensation for ux500 variant MMCI. Remove obsolete stedma40_set_psize since it is only called from pre_transfer. DMAEngine device_control replaces the functionality of stedma40_set_psize.
