iwlwifi: add PAN API

Define the new host commands and notifications
	REPLY_WIPAN_PARAMS
	REPLY_WIPAN_RXON
	REPLY_WIPAN_RXON_TIMING
	REPLY_WIPAN_RXON_ASSOC
	REPLY_WIPAN_QOS_PARAM
	REPLY_WIPAN_WEPKEY
	REPLY_WIPAN_P2P_CHANNEL_SWITCH
	REPLY_WIPAN_NOA_NOTIFICATION

and their corresponding structures along with the PAN
station flag, the PAN AP sta ID and new dev types for
the second context.
