qcacld-3.0: Support for pre CAC on SAP for user requested channel

Telusuri Sumber 
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 .
