qcacld-3.0: Add unit test framework to validate WLAN suspend/resume features

Browse Source 
WLAN suspend/resume feature has tight dependency on APPS platform
suspend/resume support. On new targets APPS suspend/resume is not
supported until target is feature complete. In absence of APPS
suspend/resume support testing WLAN offload features become
difficult. Add unit test framework to test WLAN suspend/resume
features using private IOCTL command by simulating APPS
suspend/resume behaviour.

Trigger WLAN suspend:
iwpriv wlan0 wlan_suspend 0 0

To resume WLAN run a ping test from access point side and very 1st
ping request unicast packet should trigger wake up.

If FW is not waking up APPS then use below command to do a manual
wake up:

Trigger WLAN resume:
iwpriv wlan0 wlan_resume 0 0

This unit test framework is only for SNOC.
