In sap_acs_channel_check fix ‘if’ condition will be always true for any
given channel, this will fail to validate if the given channel is in ACS
channel range.
Fix the if condition check from logical OR to AND to validate given channel
is within the ACS start and end channel range.

Add support for pre CAC on SAP for the user requested channel.
The reason for the requirement is to have SAP operations without
interruptions due to CAC. After starting SAP on the 2.4GHz
channel, the driver will start a pre CAC on the 5GHz DFS channel
requested. If no radar is detected, SAP is expected to switch
from the 2.4GHz channel to the DFS channel mentioned in the pre
CAC request. If radar is detected SAP will continue to operate on
the 2.4GHz channel. To provide the pre CAC channel to the driver,
vendor commands/attributes are used .

Ensure that the channel list used for ACS channel selection
is sorted for all the possible channel width cases. In the
current implementation, channel list sorting is not done for

ACS channel range is getting set before the 11ac override,
leading to incorrect hardware mode. Fix the same by setting
the ACS range after 11ac override and ensure that channel
list is sorted in all the valid channel width cases.

Modify the set hardware mode command sequence during channel switch
in the case of SAP/P2P-GO and STA/P2P-CLI as per the latest FW
requirements. This is primarily to accommodate the time take for
calibration during hardware mode change which could lead to
momentary data stalls.
The new sequence is as follows:
1. Send (E)CSA
2. Do vdev restart/vdev up
3. For DBS downgrade:
a. PM will initiate HW mode change to DBS right away
4. For single MAC upgrade:
a. Opportunistic timer is started, PM will check if MCC
upgrade can be done on timer expiry
The old sequence is as follows:
For MCC upgrade:
1. Send (E)CSA
2. Opportunistic timer is started
3. vdev restart is initiated on the new channel
4. PM will check if MCC upgrade can be done on timer expiry
For single mac upgrade:
