ASoC: loongson: Add Loongson-2K0300 I2S controller support

Browse source

The Loongson-2K0300 I2S interface differs significantly from the
Loongson-2K1000. Although both utilize external DMA controllers, the
Loongson-2K0300 does not require additional registers for routing
configuration.

Due to hardware design flaw, an extra controller reset sequence is
required during probe.
