cfg80211: Fix regulatory check for 60GHz band frequencies
The current regulatory code on cfg80211 performs a check to
see if a regulatory rule belongs to an IEEE band so that if
a Country IE is received and no rules are specified for a
band (which is allowed by IEEE) those bands are left intact.
The current band check assumes a rule is bound to a band
if the rule's start or end frequency is less than 2 GHz
apart from the center of frequency being inspected.
In order to support 60 GHz for 802.11ad we need to increase
this to account for the channel spacing of 2160 MHz whereby
a channel somewhere in the middle of a regulatory rule may
be more than 2 GHz apart from either the beginning or
end of the frequency rule.
Without a fix for this even though channels 1-3 are allowed world
wide on the rule (57240 - 63720 @ 2160), channel 2 at 60480 MHz
will end up getting disabled given that it is 3240 MHz from
both the frequency rule start and end frequency. Fix this by
using 2 GHz separation assumption for the 2.4 and 5 GHz bands
but for 60 GHz use a 10 GHz separation before assuming a rule
is not part of the band.
Since we have no 802.11ad drivers yet merged this change has
no impact to existing Linux upstream device drivers.

enabled by parsing eeprom data, use ATH9K_HW_CAP_ANT_DIV_COMB
which is already filled at init time.

brcmfmac: simplify handling e-scan result firmware event
Upon handling an e-scan result event from the firmware in
brcmf_cfg80211_escan_handler() the status may indicate e-scan
is completed or aborted. If so brcmf_notify_escan_complete()
is called. However, that function and brcmf_cfg80211_escan_handler()
both log the same debug message and both enable MPC flag in the
firmware.

brcmfmac: clear status for in-band interrupt in brcmf_sdbrcm_isr
SDIO in-band interrupt is level sensitive according to SDIO standard.
When the register interrupt handler gets called by SDIO stack it is
running in non interrupt context and expected to clear the interrupt
from the dongle. Therefore in-band and out-of-band interrupt need to
be handled differently.
