qcacld-3.0: optimization of p2p miracast connecting time

Browse source 
Add new parameter 128/129 for miracast command to enable/disable
p2p connection time optimization. The command needs to be issued
before p2p negotiation/invitation/connecting, the driver will do some
necessary configuration to reduce the p2p connecting time. At present,
disabling IMPS is the only configuration to achieve it.
