qcacmn: PreCAC auto channel switch support
Changes to switch to the preferred preCAC channel after the
preCAC is done.
User can configure non-DFS channel as an intermediate
channel to reduce AP bringup time, and configure the DFS
channel as usual. PreCAC Logic will use the intermediate
channel as the home channel and will prioritize the DFS channel
to start preCAC first and switch automatically after the preCAC
timeout.
Command to configure intermediate non-DFS channel
iwpriv wifiX interCACChan <non-DFS channel num>
Assumption:
Intermediate channel should be configured before configuring
the DFS channel as operating channel.
