wlan_platform: use cnss_utils to send device type across wlan & bt

Browse Source 
Add code to use cnss_utils to send device type across wlan & bt.
cnss platform driver reads the wlan sw control gpio and updates
the cnss_utils with the device type, when Bt comes up it get the
device type from cnss_utils.
