dmaengine: loongson2-apb: Rename the prefix ls2x to loongson2 



Since commit e06c4323 ("dmaengine: Loongson1: Add Loongson-1 APB DMA
driver"), the Loongson-1 dma controller was added.

Unfortunately their naming has not been standardized, as CPUs belonging
to the same Loongson family, we expect to standardize the naming for
ease of understanding.
