Add "loongson,ls2k0300-i2s" dedicated compatible to represent the I2S interface of the Loongson-2K0300 chip. The hardware integration of the Loongson-2K0300 I2S interface differs significantly from that of the Loongson-2K1000. Specifically, while both utilize external DMA controllers, the Loongson-2K0300 configures DMA channel routing via the `dmas` property, whereas the Loongson-2K1000 requires additional register.
Can this patch be the second one? Huacai
