This patch set flushes all data and management packets before
suspend, so the 500ms delay workaround in ath12k_core_suspend
is not needed and removed.

Due to MHI bugs, at the moment we are not able to shutdown and
fully power off the device. As a workaround we put firmware to
WoW state to make sure no unexpected activities while host is
in suspend.

With all suspend/resume functionality implemented, we change
supports_suspend to true for WCN7850 to make it work.

  wifi: ath12k: Flush all packets before suspend
  wifi: ath12k: Put firmware to WoW state during suspend
  wifi: ath12k: Turn on suspend/resume switch for WCN7850
