This is to make it configurable by firmware IEs. Also determine if we need
to write or read the board address to the chip by checking if board address
is set or not.

In some rare cases core code needs to know what hif type is used. Add
a field to struct ath6kl to denote that. Hopefully this is just a
temporary solution.

The target triggers sdio data line to wake up the host when
WOW pattern matches. This causes sdio irq handler is being
executed in the host side which internally hits ath6kl's RX path.

WOW resume should happen before start processing any data from
the target. So it's required to perform WOW resume in RX path.

This area needs bit rework to avoid WOW resume in RX path,
As of now it's fine to have this model, rework will be done later.

This is to force ath6kl to power off hardware during suspend even if
sdio support keep power. This is needed, for example, when sdio
controller is buggy or maximum powersaving is desired.

Usage:

insmod ath6kl.ko suspend_cutpower=1

If sdio controller doesn't support keep power, cut power from hardware
during suspend and restart firmware during resume. If we are connected
during suspend, send a disconnected event to user space.

Earlier suspend failed with an error if sdio didn't support keep power.
Now suspend will happen succesfully even with that case.

This way it's easier to track state changes and in the future add
more warnings about using hardware in wrong states. Currently there
are few random flags for trying to do the same, those will be cleaned
and removed in the future.

This is in preparation for cutpower suspend feature. HIF layer makes
the decision based on information provided by cfg80211 and what hardware
actually supports. Then it calls ath6kl_cfg80211_suspend() to enable
the chosen mode.

Functionality should be the same, this is just preparation for
more suspend modes (cutpower and wow).

The benefit from this is that user space can control hardware's power state
by putting interface up and down. This is handy if firmware gets to some
weird state.

The downside will be that putting interface up takes a bit longer,
I was measuring ~500 ms during interface up.

Even though only a single concurrent remain-on-channel operation is
supported, there may be two pending remain-on-channel events (one to
indicate end of a canceled operation and another to indicate start of a
new operation). User space won't be able to distinguish these events
unless unique cookies are used.

The previous behavior resulted in wpa_supplicant getting quite
confused about the driver's offchannel state in various sequences
and this made the P2P state machine behave incorrectly. Use of
more than a single remain-on-channel cookie value fixes this.
