[Impact]
Qualcomm WCN6856 doens't work.

[Fix]
Backport missing bits to make Wifi 5 work. Wifi 6 support is not in the
scope of this SRU.

[Test]
The system can connect to Wifi. Wifi still works after several rounds of
suspend/resume cycles.

[Where problems could occur]
The change is limited to ath11k, which is also the only user of mhi bus,
so the scope of risk is limited. Let alone it never worked before, so
there's not much room to go wrong.

  bus: mhi: core: Add support for forced PM resume

Wen Gong (2):
  ath11k: add string type to search board data in board-2.bin for
    WCN6855
  ath11k: change to use dynamic memory for channel list of scan
