[PATCH] wireless-regdb: update US rules for 5600 MHz - 5650 MHz

["Luis R. Rodriguez" <lrodriguez@atheros.com>]

The FCC is trying to assist airports that use Terminal Doppler
Weather Radar (TDWR) systems in avoiding interference with
some outdoor wireless systems operating in the 5.4 GHz
(5470 MHz - 5725 MHz) band. One of the things they have decided
on is to disallow operation on the 5600 MHz - 5650 MHz frequency
range inclusive. What this means in practice is 5 GHz 802.11
devices programmed to operate in the US will have these
channels now disabled:

 * 5600 MHz [120] (disabled)
 * 5620 MHz [124] (disabled)
 * 5640 MHz [128] (disabled)

Channel on 5660 MHz (132) will be left enabled as the channel
bandwidth is 20 MHz for legacy 802.11 networks but note that
HT40- will be disallowed for that channel. The HT40+ and HT40-
allowed channel map obviously changes. This is computed
dynamically on cfg80211 based on your allowed channel list.
For a US based device this is what you will get now
(excerpt from on /sys/kernel/debug/ieee80211/phy0):

 .. etc ..
5540 HT40 -+
5560 HT40 -+
5580 HT40 -
5600 Disabled
5620 Disabled
5640 Disabled
5660 HT40  +
5680 HT40 -+
 .. etc ..

The details on which this patch is based on is documented on
the FCC Knowledge based Publication Number: 443999 [1]
