qcacld-3.0: wma: Featurize Green AP service event handling

Currently wma_update_hdd_cfg() has unconditional code to check for
firmware support of the WMI_SERVICE_EGAP service and to register an
event handler when it is present. However this code doesn't build
correctly when the Green AP feature is disabled in the build.
Therefore featurize the Green AP service event handling.
