The tx interrupt for beacon queue is configured only for edma chips.
As the edma chip does not support per descriptor interrupt, no need to
set INTREQ for every beacon descriptor. And also clear ps filter for
beacon frame.

Sync-up ibss beacon timer with the beacon frame's timestamp. When the
node acts as joiner, it has to sync with the received beacon timestamp
instead of reading tsf from hw. As the hw tsf wont wont be update till
bssid is configured. This patch programs hw tsf with the received beacon
timestamp if beacon timers are yet to be configured.

The driver provides a regulatory hint to cfg80211 as obtained from the
SPROM. Mostly, this will be a two-letter ISO country code. However, it
may obtain special country code similar to the world regulatory domain
as used in cfg80211. This patch avoids setting these special codes as
the hint is lost to cfg80211.

The brcmsmac driver provides the country code from sprom as a regulatory
hint to cfg80211. When brcmsmac does not find a country code entry in
the sprom it passes 'US' as regulatory hint. Better approach is to rely
on the world regulatory domain in cfg80211/crda.

The MAX_TXPWR table for BTCOEX is not needed for AR9462.
Programming these values to the HW results in undesirable
behavior - for example, large number of delimiter/data
underruns are seen in AES-CCMP mode. Also, registers like
AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX
power table is programmed to the HW, and frames being transmitted
end up being looped back to the RX engine, an example being beacon
frames in IBSS mode.
Remove this table for now - this fixes CCMP performance and general
IBSS usage.
