When BW Expansion feature is enabled using UCI or cfg80211tool
command, the utility function to set/get the BW Expand feature
is introduced inside DFS module.
A new dfs member dfs_use_bw_expand is used to store the status
of BW Expansion feature.

The BW Expansion feature requires Agile SM to run on User
Configured Channel. The User configured Frequency and Phymode
should be stored in DFS structure.
Introduce the following new DFS structure members:
User configured Frequency - dfs_bw_expand_target_freq
User configured mode - dfs_bw_expand_des_mode
The API dfs_is_subset_channel_for_freq is changed from static to
non-static. The API dfs_is_subset_channel_for_freq is needed for
finding the channel to run Agile when Bandwidth Expansion feature
is enabled.

Replace qdf timers with HR timer for pre CAC timeout and process
the preCAC completion work in workqueuecontext.
Since preCAC expiry is processed in H/W interrupt context
(while using HR timers), no other timer cancellation is allowed
('qdf_hrtimer_cancel' function will wait for the handler finish)
But if we process the preCAC timer completion work in H/W context,
other timer cancellation will take time. To fix this, process the
preCAC completion work in workqueue context to allow other timer
cancellation.

When AP moves from DFS to NON-DFS channel, dfs chan state is
not updated and have state DFS_CAC_STARTED. Similarly, if the VAP

DFS_CAC_STARTED.
During CAC STOP, send the DFS event CAC RESET to change the dfs

High CAC timeout is seen for weather and non-weather DFS channels.
This is due to the delay in 5.4 Kernel timers. There is 1 second delay
observed for every 60 seconds.
To fix this issue, replace qdf timers with HR timer for CAC timeout.
On CAC expiry, when VDEV UP is sent to FW, serialization timer is
cancelled. Since CAC expiry is processed in H/W interrupt context
(while using HR timers), no other timer cancellation is allowed.
Hence, process the CAC timer completion in work queue context to allow
other timer cancellations by the CAC thread.

Use DFS curchan and prevchan to deliver DFS CAC Events.
When CAC is started, deliver WLAN_EV_CAC_STARTED on all the sub-channels
of the current channel. In order to reset the CAC_DONE state of the
previous channel, deliver the WLAN_EV_CAC_RESET event on all the
sub-channels of previous dfs channel. If the previous channel was non-dfs
channel the CAC_RESET event need not be delivered. Since in the case of
ETSI domains retain the CAC_DONE state CAC_RESET event need not be
delivered for this case too.

The "wmi_pdev_dfs_radar_detection_event" has an unused field "chan_freq".
It currently holds the value of primary 20MHz channel. With the
introduction of 11BE chipsets, this field is changed to hold the value of
the center frequency of the channel width on which the radar is found.
This new change is indicated by a wmi service
"wmi_is_radar_found_chan_freq_eq_center_freq".
For the Chipsets that support this service, the radar found frequency
can be calculated by mere addition of the fields "chan_freq" and
"freq_offset" field.

Following are the changes:
1. Add macros relevant to the addition of the 320 MHz root to the preCAC
tree.
2. Adding 320MHz bandwidth in switch case and separating
'case CH_WIDTH_320MHZ' using a compile time macro ( 11BE), forces us
to use the macro inside the function, which is not allowed by the
coding guideline.
Convert the "switch case" mapping (which is generally a binary search)
into a linear search of a mapping (BW -> bonded pair) array , thereby
using the macro WLAN_FEATURE_11BE to separate the 320MHz bandwidth
in the data structure space instead of doing the separation inside
the function space.
