rsi: add/remove interface enhancements for p2p

Browse Source 
STA_OPMODE and AP_OPMODE macros are renamed to RSI_OPMODE_STA
and RSI_OPMODE_AP. New opmodes are added to this list for P2P
support. Mapping of mac80211 interface types to rsi interface
types are added.
Add and remove interface callbacks are handled for P2P mode.
