cnss2: Add daemon_support dts option for QCA6390 



ENABLE_DAEMON_SUPPORT is by default enabled. For platforms where
cnss_daemon is not needed, number of qmi clients will be 2 and
WLAN FW will then wait for cnss_daemon to be connected and CNSS2
will timeout waiting for FW ready. Thus add a dts option to enable
daemon_support.
