qcacld-3.0: Remove hardcoded value and set qpower appropriately
This is a qcacld-2.0 to qcacld-3.0 propagation.
The issue is when host re-enables QPower after resume, it is setting
WMI_STA_PS_ENABLE_QPOWER to 1 (which is for QPower = 2) always and never
WMI_STA_PS_ENABLE_QPOWER to 2 (which is for QPower = 5).
This means one suspend/resume is enough to disable QPower = 5 and
change to QPower = 2.
Fix this by removing the hardcoded value of 1 and use qpower_config instead.
