Change the commands and events according to the new fw api
(fw >= 6/7.3.0.0.75).

The main change is the replacement of JOIN/DISCONNECT commands,
with ROLE_START/ROLE_STOP commands.

The use of these commands should be preceded by the ROLE_ENABLE
command (allocating role resources), and followed by the
ROLE_DISABLE command (freeing role resources).

Update the acx commands according to the new fw api
(fw >= 6/7.3.0.0.75).

The main change in most of the ACXs is the addition
of a new role_id/link_id field, which is required
for multi-role operation.

Currently, we don't really support multi-role, as
most of our data (inside wl) is global.
As the current fw doesn't support concurrent roles
yet, keep it this way and add wl->role_id and
wl->sta_hlid to save the active role/link.

When toggle_irq is called for PCI devices to disable device interrupts
it used tasklet_disable to wait for a possibly running tasklet to finish.
However, on SMP systems the tasklet might still be scheduled on another CPU.
Instead, use tasklet_kill to ensure that all scheduled tasklets are finished
before returning from toggle_irq.

Furthermore, it was possible that a tasklet reenabled its interrupt even
though interrupts have been disabled already. Fix this by checking the
DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts
during tasklet processing.

While at it also enable/kill the TBTT and PRETBTT tasklets in the
toggle_irq callback and only use tasklet_kill in stop_queue to wait
for a currently scheduled beacon update before returning.

Modify the driver so that it does not function when the interface is
down, in preparation for runtime power management.

No commands can be run while the interface is down, so the ndo_dev_stop
routine now directly does all necessary work (including asking the device
to disconnect from the network and disabling multicast functionality)
directly.

power_save and power_restore hooks are added meaning that card drivers
can take steps to turn the device off when the interface is down.

The MAC address can now only be changed when all interfaces are down;
the new address will be programmed when an interface gets brought up.
This matches mac80211 behaviour.

Also, some small cleanups/simplifications were made in the surrounding
device handling logic.
