net80211: update for (more) VHT160 support

[bz]

Summary

Implement two macros IEEE80211_VHTCAP_SUPP_CHAN_WIDTH_IS_160MHZ()
and its 80+80 counter part to check in vhtcaps for appropriate
levels of support and use the macros throughout the code.

Add vht160_chan_ranges/is_vht160_valid_freq and handle analogue
to vht80 in various parts of the code.

Add ieee80211_add_channel_cbw() which also takes the CBW flag
fields and make the former ieee80211_add_channel() a wrapper to it.
With the CBW flags we can add HT/VHT channels passing them to
getflags() for the 2/5ghz functions.

In ifconfig(8) add the regdomain_addchans() support for VHT160
and VHT80P80.

With this (+ regdoain.xml updates) VHT160 channels can be
configured, listed, and pass regdomain where appropriate.

Ignore the pci.h additions here; arc diff --create --base=git:<branch> does not do what I thought it would. Sorry.

Remove line before commit from this branch as well.

sys/net80211/ieee80211_regdomain.c

160–161

I should commit these whitespace changes separately upfront as well.

Remove extra debug line from this branch as well.

• Remove debug printfs from here as well.
• Remove the whitespace from regdomain.

Anyone interested in reviewing this? I'd love to get it in no later than Monday.
