qcacld-3.0: Update correct wiphy band capabilities

Browse Source 
Driver is updating wiphy band capabilities incorrectly as
it is always updating 2G band as always supported, in case
if 2G band is disabled from ini "BandCapability", driver
should not update 2G band capabilities to wiphy.

To avoid above issue, add a api to check if 2G band is
supported and then only update 2G band capabilities to
wiphy.
