P2P: Add support for VHT 80+80 MHz and 160 MHz
The new max_oper_chwidth and freq2 arguments to P2P_CONNECT, P2P_INVITE, and P2P_GROUP_ADD control interface commands can be used to request larger VHT operating channel bandwidth to be used than the previously used maximum 80 MHz. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
