qcacmn: Set the VAP flag to block Tx after radar is hit

The change 'I4acd2f70707386f731e9b8fa2ef90a37868cbe23'
makes modifications in MLME and DP (Data Path) to optimize
the check for radar in per packet transmission path to
reduce CPU processing overheads. This new check is based on
a VAP variable that indicates whether radar is detected
or not.

Upon radar detection, send an indication to MLME through the
registered callbacks to update the status of the flag.

qcacmn: Validate the proposed bitmap and enable puncturing

When radar is found in any DFS channel, a radar bitmap is
generated based on the radar infected channels. For example,
if operating channel is 100 HT160 and radar found in 112,
then the generated bitmap is B0000_0010. This proposed bitmap
is compared with the valid puncturing patterns. In this case,
the proposed bitmap is valid puncturing pattern.

In case of a valid puncturing pattern, send the final
bitmap to DFS module and the module updates the DFS channel
puncturing pattern. If an invalid puncturing pattern is
found, return value zero and do not update DFS channel
puncturing pattern.

qcacmn: Reinit DFS after HW mode switch (phase 2)

Supported dynamic HW mode switches:
DBS (full band 5G and 2G) <-> DBS_SBS (low band 5G, high band 5G and 2G)

Description of the changes:

1. NOL conversion:
a. Introduce a temporary NOL list copy structure in DFS psoc obj.
b. When mode switch is triggered:
i. Stop the NOL timers and clear the data, to avoid processing NOL
expiry during mode switch.
ii. Allocate the psoc NOL copy for the target num_radios.
iii. Store the NOL data of each radio to the target pdev ID
(pdev ID after mode switch) in the psoc NOL copy,
using a unified mux/demux API.
c. After mode switch is completed:
i. Resume NOL by re-initializing the list from the temporary psoc
copy.
ii. Free the psoc copy after mode switch is complete.
iii. Note: changes are made to support pause and resume of NOL,
increasing NOL timeout by a few milliseconds.

2. PreCAC list conversion:
a. When mode switch is triggered:
i. Stop the existing preCAC timer and send ADFS abort command to FW.
b. When mode switch is completed:
i. Unify/separate the preCAC list if the target mode is DBS/DBS_SBS
respectively, using a single API.
ii. Start ADFS again.

3. Radar detection lock:
a. While detecting radar, acquire a lock to avoid handling user triggered
mode_switch during this process. Release the lock once radar
processing is completed and CSA start is triggered.

4. Radar detection/CAC completion defer during mode switch:
a. While detecting radar or CAC completion, check if mode switch is
in progress. If yes, defer the processing and wait for mode switch to
complete before handling the events.
b. Note: Precedence is Radar over CAC, i.e., if CAC processing is waiting
and radar is received, CAC completion is no longer handled.
