Use device role for scans when the sta is not
associated.

sched_scan is used only when the sta is
not associated, and thus should use
the dev role (instead of sta role).

The set_template commands now takes the role_id as
parameter.

Usually, we'll use the vif's main role_id.
However, sometimes we'll want to use
wlvif->dev_role_id instead of wlvif->role_id,
so pass the wanted role_id as param.

Update WL127X_FW_NAME/WL128X_FW_NAME.

(This commit starts a series of fw update patches,
and changes the start() callback to return an error
in order to prevent the use of the driver during the
transition. This change will be reverted in the
last patch of series)

Device role is always started along with ROC.
Couple them together by introducing new wl12xx_start_dev
and wl12xx_stop_dev functions.

By using these functions, we solve a bug that occured during
channel switch - we started the dev role on one channel, and
ROCed on a different one.

Separate the debugging macros and other definitions to a new debug.h
file.  This is be needed because the sdio and spi modules don't need
to depend on the wl12xx module anymore, but still need to include
wl12xx.h.  Currently they do depend on it, because of the debugging
global that wl12xx exports.  A future patch will remove this
dependency.

wl->vif is appropriate only when a single vif is being used.
Instead, pass wlvif as parameter or iterate through all
the vifs (e.g. when a global configuration was changed)

Leave wl->vif only to determine whether a vif was already
added (this check will be removed as well after both the
driver and fw will support multiple vifs)

Use it instead of wl->mac_addr.

It seems that due to some fw bug, we still need to set nvs->mac

Thus, use wl->mac_addr for this purpose, and don't delete it yet.

The ROC command asks the fw stay on the channel of the given
hlid. it currently has 2 primary functions:

1. Allow tx/rx from the device role.

In order to tx/rx packets while the stations is not associated
(e.g. auth req/resp), the device role has to be used, along
with ROC on its link.

Keep the logic similiar to the one used in dummy_join. However,
since we can't scan while we ROC, we add CROC before starting
a scan, and ROC again (if needed) on scan complete.

2. Keeping the antenna for a specific link.

We ROC until the connection was completed (after EAPOLs exchange)
in order to prevent BT coex operations from taking the antenna
and failing the connection (after this stage, psm can be used).

During association, we ROC on the station role, and then CROC
the device role, thus assuring being ROC during all the connection
process.

Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap
to indicate what roles are currently ROCed.

Add wl12xx_roc/croc functions in order to wrap the roc/croc
commands while taking care of the roc bitmap.

The current ROC/CROC state-machine is a bit complicated. In
the future we'll probably want to use wpa_supplicant to control
the ROC during connection.
