77561584ad qcacmn: Define DFS logging APIs
1) Define logging(alert, err, warn, info, debug) on top of
   QDF abstractions for DFS component.
2) Use dfs_info for important prints such as CAC timeout,
   NOL timeout, enable/disable radar etc.
3) For everything else use dfs_debug macro.

09e53bd45c qcacmn: Wait for 2secs before sending CSA
Reverse CSA:
===========
Problem:
When Repater detects the RADAR, it sends RCSA to RootAP and
immediately switches to a new channel without waiting for CSA
from Root AP.

Expected behaviour:
When Repeater detects the RADAR, if uplink is present then it sends
RCSA to RootAP and waits for 2secs to receive CSA. If Repeater
does not receive CSA in 2sec, choose a random channel and
bring up the AP vap.

Solution:
In Repeater, if RCSA is sent successfully to RootAP then wait for
2secs to receive CSA from Root else choose a random channel and
bring up the vaps.

76192e12a9 qcacmn: Register a DFS callback function to get AP CAC status
In Repeater AP scenario, when STA vap starts scan, it calls this
registered DFS callback function to get the AP CAC status. If the
AP vap is performing CAC, STA vap does not start SCAN.

c2fc6d09c6 qcacmn: Fix DFS kernel panic
Analysis:
dfs_nol_timer_cleanup() calls dfs_nol_update(), which internally
calls a legacy function to update the scan channel list and sends
a WMI command to FW. However, from WIN side dfs_nol_timer_cleanup()
is also called after target stop, which leads to a kernel panic.

Solution:
Call dfs_nol_update() prior to target stop.

Initalize precac channel list during dfs reset.

ff86e37d20 qcacmn: Fix connection information deleting and restoring
Currently only one connection information corresponding to the
provided mode is deleted and restored, which causes channel
selecting failure in DFS testing with AP+AP concurrency mode.
When radar is found in AP+AP concurrency mode, a new valid channel
should be selected. Before selecting the channel, all existing
connection information of SAP mode should be deleted, otherwise
no valid channel can be selected.

All the connection information corresponding to the provided mode
should be deleted and restored.

877f3236d8 qcacmn: Refactor dfs cac timer and other logic in dfs component
It is possible to use host based cac timer even for the dfs
offload, So make sure to do all initialization for cac timers.

Also store dfs offload flag in dfs component.

fe7233a795 qcacmn: Fix DFS kernel panic
As part of DFS component destroy, "ic" is accessed to reset
NOL list and PRECAC channel list, but "ic" is already deleted
as part of MLME component destroy. And therefore invalid memory
access happens.

Reset NOL list and PRECAC channel list before "ic" deletion.
