When we are scanning for the wildcard SSID in a scheduled scan, we
should use SCAN_SSID_TYPE_PUBLIC so that we don't filter out the scan
results.
Signed-off-by: NLuciano Coelho <coelho@ti.com>

The wl12xx firmwares support multiple SSIDs in a single sched_scan
run.  This patch implements support for it.

We use three different types os sched_scan: FILTER_ANY (ie. not
filtering, only wildcard SSID in the probe_reqs); FILTER_LIST (ie. send out
probe_reqs with the specified SSIDs and only report if they are
found); and FILTER_DISABLED (ie. send out probe_reqs with the
specified SSIDs, but report anything found).

Since we still don't have proper filter support in nl80211/cfg80211
yet, we cannot use filters when the wildcard SSID is used.  Thus, we
will not filter anything if the wildcard SSID is specified.

When selecting packets for transmission, prefer the ACs that are least
occupied in the FW. When packets for multiple ACs are present in the FW,
it decides which to transmit according to WMM QoS parameters.

priority traffic is present.

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.
