[PATCH 02/11] brcmfmac: use different fw api for encryption,auth. config

["Arend van Spriel" <arend@broadcom.com>]

From: Hante Meuleman <meuleman@broadcom.com>

This patch changes the commands being used to configure
encryption and authentication. These new methods are needed
for when p2p and hostap support are added.
