Avinash Patil 1fe192d8d6 mwifiex: selectively choose ext_scan support 
Some devices do not support extended scan.
This patch adds support to enble ext_scan selectively.
For SD/PCIe interfaces, deefine ext_scan_support as part of
card structure and use it to initialize ext_scan in adapter
during registering device. For USB interfaces, we initialize
ext_scan during register_dev handler.
