qcacmn: Enable notify-frame feature in FW

Enable bits in WMI_INIT command to let the FW know about host's
capability to support notify frame feature. If the feature is enabled,
host can mark certain TX frames as "notify frames" for hardware and they
need not be sent to FW. FW depends on this capability exchange to decide
whether to install HW rules for frames to be sent to HW.
