mwifiex: support for creation of AP interface

Browse Source 
1. wiphy structure is per device; hence moved it to mwifiex_adapter
mwifiex_register_cfg80211 takes mwifiex_adapter as parameter.
This function only registers wiphy with cfg80211.
2. Creation of interfaces is moved to cfg80211 add_virtual_interface
handler.
3. Create 2 interfaces by default: station and AP
