[PATCH] wireless: Changes to ieee80211.h for user space regulatory daemon

Attached are two small patches for include/net/ieee80211.h to prepare
for later submission of code to implement a user-space daemon that
supplies 802.11 regulatory information.

The first change adds a bit indicating that 802.11h rules are to be
applied to a channel. As discussed earlier in this list, a single bit
is unlikely to be sufficient; however, at this time I have been unable
to find any regulations implementing differences between 802.11a and
802.11h other than DFS, radar detection and passive scanning. A single
bit is thus sufficient to convey to the driver that these rules should
be obeyed.

The second change adds comments to the freq and max_power fields of
struct ieee80211_channel to indicate the units that are used.
