qcacld-3.0: Ini bitmap to enable/disable a particular NAN feature

NAN protocol runs in firmware and controlled by framework.
Framework configures multiple NAN discovery params while enabling
NAN. Framework configurations would be based on the framework
constraints or realtime scenarios like resource(memory/power/..)
consumption. But some of these params might need to be controlled
explicitly based on the usage.
NAN DW is one such parameter, which is configured as 4 seconds
when the device is in sync role and the screen is off. But
for some usecases, this param might have to be 512ms always
irrespective of screen off/on for some targets. Add an ini param
"nan_feature_config" to set a bit to indicate firmware whether to
honor framework configured DW value or the firmware default value.
Send the vdev param on NAN supported vdev by setting the "bit 0"
to indicate firmware to allow framework configured DW value.
If this bit is not set, firmware shall consider its default value.
