The baseband and cycle counters are being sampled during ani
processing for debugging purpose. Whenever the ani is postponded
due to sleep state, taking samples on that time is of no use and
also unneccesarily waking up the chip might increase the power
consumption on idle associated state. Hence moving debug function
within powersave block.

When WLAN enter full sleep mode, WLAN HW should send out a LNA_TAKE
message for BT to take control of the shared LNA. Otherwise BT traffic
is completely stopped whenever the wlan interface is moved full sleep
mode.

During driver stop, btcoex is disabled and also btcoex_hw.enabled
is set to false. Afterwards mci_is_enabled returns false so that
BT is not gaining SPDT control on WLAN sleep. Fix that.

WLAN driver initialization is muting BT which is terminating
the ongoing BT traffic. The reason to mute BT is to avoid any
incoming MCI messages from BT when MCI reset is in progress that
could corrupt WLAN MCI RX state machine. But we should not
dedicate radio completely to WLAN in driver init itself. So this
patch removes the wlan weightage changes from mute BT to retain
BT connection.

Two MCI interrupts are generated while adding A2DP and headset profiles
with different types and same connection handle. While disconnecting,
only one MCI interrupt is generated with last added profile type value
for both profiles.
While adding second profile type decrement first one.

Firmware supports changing filters using ACX_RX_CFG command,
so use it in .configure_filter callback. Firmware also supports
probe request filtering, so add it too along the way.
This will also re-enable BSSID filter which is now removed by
join command while associating.

This driver has a hack in cmd.c which effectively disables all filtering.
This seems to be triggering a firmware bug where it stops reporting any
rx packets after random time on some routers, which is eliminated (or at
least appears much more rarely) when filtering is on.
I have found that only BSSID filter needs to be disabled for association
to work, so disable only that instead of all filtering.

The brcmsmac internal regulatory data is being used to determine whether
OFDM should be allowed, and this is only done once during
initialization. To be effective this needs to be checked against
mac80211's regulatory rules for the current channel.

Currently the limits from the internal X2 domain are used, regardless
of what regulatory rules are in effect. Instead use the power limits set
by the higher-level regulatory support.
The rules for the MIMO power limits are still always derived from the
world domain, pending guidance from Broadcom as to how these need to be
handled. This will be fixed later, but using the limits from the world
domain works for now.

Currently the radio disable state is only updated during initialization,
and it's only checked against the internal world domain. This is
unnecessary, as there are always valid channels against this domain.
Instead, check whether any channels are enabled in the regulatory
notifier and update the radio state accordingly.

brcmsmac implements enforcement of regulatory constraints internally,
using a Broadcom-specific world roaming domain named X2. Besides being
duplication of functionality this can also conflict with mac80211's
regulatory implementation, as mac80211 is unaware of the X2 domain and
thus might apply a more restrictive domain.
This patch is the first step in making brcmsmac cooperate with
mac80211's regulatory support. X2 is registered as a custom domain with
mac80211, so that at least both implementations will be enforcing the
same set of constraints. The internal enforcement of rules is kept for
now; this will be converted over to relying on mac80211 regulatory
enforcement in later patches.

This code has been kept around in anticipation of adding support for
40MHz channels, but subsequent patches to better integrate with mac80211
regulatory support will render it completely broken. Therefore we should
go ahead and remove it.
Keep these changes separate from other cleanup patches in order to make
it easier to resurrect 40MHz channel support at some point in the
future.

In some situations brcmsmac is choosing a channel internally. This makes
it difficult at times to know what channel to use for enforcing
regulatory constraints, so instead always use the channel from the
mac80211 configuration.

This code is unnecessary, and in fact it's never executed because the
interface is never up when brcms_c_channels_commit() is called. Removing
it helps simplify the implementation of proper regulatory support.
