ASoC: rockchip-i2s: fix registers' property of rockchip i2s controller
Reference rockchip I2S controller TRM, modify some registers' property
I2S_FIFOLR: read / write, but not volatile, not precious
I2S_INTSR: read / write
I2S_CLR: volatile, register value will be cleared by read
Test on RK3288 with max98090.
