wlan: Use wcnss driver's control interface

Setup the parameters required by wcnss driver thru the control
interface; serial number (for MAC address auto-generation), calibrated
data availability etc. are some of the parameters configured thru this
interface.  These parameters were earlier written thru module parameters,
however that required the wcnss service daemon to have the root permission.
