qcacld-3.0: Limit SAP channel to 1-11 for 2.4GHz
There are many legacy clients which supports 2.4GHz but
don't support channel 12 and 13 (or does not have the capability
to detect country change where channel 12 and 13 is valid).
In that case, if SAP comes up on channel 12/13, those legacy
clients won't be able to connect to AP.
Hence, remove channel 12/13 from the ACS channel list in 2.4GHz
