qcacld-3.0: Add VHT capability in the wiphy for 2.4ghz

Currently the driver is not included the VHT capability
on 2.4ghz band if gEnableVhtFor24GHzBand ini is enabled.
As a result the driver is not advertising the VHT support
on 2.4ghz band in wiphy per band info even gEnableVhtFor24GHzBand
ini is enabled.

To resolve this, add VHT capability in the wiphy for 2.4ghz
