wifi: ath11k: Suspend hardware before firmware mode off for WCN6750
During rmmod, the ath11k host driver sends a QMI MODE OFF command
to firmware.
As part of this command, firmware initiates WLAN de-initialization
and accesses certain UMAC registers during this process.
Currently, on WCN6750 WLAN hardware, the system is in a sleep state when
firmware receives the QMI MODE OFF command.
This results in a firmware/hardware reset while accessing the UMAC hardware
registers during sleep state.
To avoid this, add logic to send WCN6750 hardware specific
WMI_PDEV_SUSPEND_AND_DISABLE_INTR command to firmware prior to sending
the QMI MODE OFF command.
This will cause firmware to cease all activities and put the device in
a powered-on state that prevents access to registers which have been
powered off.
