For runtime suspend/resume, it is some different with suspend/resume,
e.g. codec power supply won't be switch off, codec jack detection
still working(to wake up system from Jack event), won't call call
snd_soc_suspend/resume, etc.

So here, we add a platform PM status, HSW_PM_STATE_RTD3, to make
the status more clear, when in idle, it will enter this status, to
transfer from HSW_PM_STATE_RTD3 to HSW_PM_STATE_D3, we will do those
extra jobs, and vice versa for resuming.

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.
