Currently, WLAN chip is powered once during driver probe and is kept
ON (powered) always even when WLAN is not active; keeping the chip
powered ON all the time will consume extra power which is not
desirable on a battery operated device. Same is the case with non-WoW
suspend, chip will not be put into low power mode when the system is
suspended resulting in higher battery drain.

Send QMI MODE OFF command to firmware during WiFi OFF to put device
into low power mode.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
