ASoC: rt5670: Keep sysclk on if JD func is used
System clock is necessary for rt5670 JD function. We assume system clock source will be set in machine driver. So there are two things left we should do in codec driver. 1. Set sysclk to codec internal clock in probe since machine driver may not do that before JD function is registered. 2. Power up PLL once sysclk source is switched to PLL.
