This series adds support for low power D0i3 mode which lets audio controller perform stream and non streaming usage scenarios while being in lower power D0i3 state.
In this series, first we modify the sst_ipc_tx_message() API to check if the DSP is in lower powered D0i3 mode or not and if so bring it to active before sending any messages. This is followed by a new API sst_ipc_tx_message_nopm() to send message without checking the new PM method.
Then we start adding D0i3 refcounting which decides the entry to D0i3 mode based on capability. This is derived from topology data. The new IPC to enter D0i3 is also required.
Finally we remove unwarranted pci device enabling calls on suspend.
