ALSA: hda - Haswell converter power state D0 verify
Haswell converters maybe in wrong power state before usage.
i.e. only converter 0 is in D0, converter 1/2 are in D3.
When pin choose converter 1/2, there's no audio output, this
cause dependency when playing differnt stream on pins.
AUD_PWRST ConvertorA_Widget_Power_State_Current D0
AUD_PWRST ConvertorA_Widget_Power_State_Requsted D0
AUD_PWRST ConvertorB_Widget_Power_State_Current D3
AUD_PWRST ConvertorB_Widget_Power_State_Requested D3
AUD_PWRST ConvC_Widget_PwrSt_Curr D3
AUD_PWRST ConvC_Widget_PwrSt_Req D3
This patch check converter's power state and set D0 if it's in D3 mode.
