The Loongson I2S platform driver (used on LS2K1000, LS7A etc.) relies on an external DMA engine (e.g., dw_dmac) rather than the internal DMA. However, its DMA-related code was originally embedded in loongson_i2s_plat.c, duplicating logic that should be shared. Extract the external DMA (eDMA) support from the platform driver and move it into loongson_dma.c alongside the existing internal DMA (iDMA) code. This change eliminates code duplication and prepares for future consolidation of DMA selection logic.
