qcacld-3.0: Add support to enable WLAN HW

As part of protected dynamic interface control feature,
if the user space disables WiFi, then the platform driver
disables the WLAN HW as well. Until the user enables WiFi,
the WLAN HW stays disabled.

So, add support to enable the WLAN HW, when the WiFi is
enabled by user space.
