wlan: add support for vendor specific event

Add support for vendor specific event and use it to provide
interfering frequency information to userspace. Userspace should
stop P2P-GO, in case P2P-GO is operating on interfering frequency
and restart P2P-GO by avoiding interfering frequency range(s). User
space may decide to continue operation on interfering frequency,
but in such case, there might be impact on performance.
