Now that the MHI&QRTR patches [1] are merged, we can add suspend/resume support for ath12k. The whole design is quite similar to that in ath11k: firmware is powered down when going to suspend and powered up when resume, this makes hibernation work as well in addition to suspend. To summary, this series first does some preparations in the first 8 patches. Then in patch [9/10] suspend/resume callbacks are implemented. And at last in [10/10] we enable suspend/resume functionality for WCN7850 because it's the only chip supporting it for now.
