cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flag
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set
maximum available bandwidth should be calculated base on
contiguous rules and wider channels will be allowed to cross
multiple contiguous/overlapping frequency ranges.
In case of old kernels maximum bandwidth from regulatory
rule will be used, while there is no NL80211_RRF_AUTO_BW flag.
This fixes the previous commit 9752482083066af7ac18a5ca376f
("cfg80211: regulatory introduce maximum bandwidth calculation")
which was found to be a problem for userspace API compatibility.
