mac80211: brcmfmac: add 2 more recent changes

Browse Source 
First one is a fix for reporting channels to the user space. Important
for users as they could try setting invalid channel and fail to start an
interface.

Later is a support for newer FullMAC chipset firmwares.

Subject: [PATCH] brcmfmac: fix reporting support for 160 MHz channels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Driver can report IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ so it's
important to provide valid & complete info about supported bands for
each channel. By default no support for 160 MHz should be assumed unless
firmware reports it for a given channel later.
This fixes info passed to the userspace. Without that change userspace
could try to use invalid channel and fail to start an interface.

Subject: [PATCH] brcmfmac: support STA info struct v7
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The newest firmwares provide STA info using v7 of the struct. As v7
isn't backward compatible, a union is needed.
Even though brcmfmac does not use any of the new info it's important to
provide the proper struct buffer. Without this change new firmwares will
fallback to the very limited v3 instead of something in between such as
v4.
