qcacld-3.0: add gEnableCckTxFirOverride ini item

When operating in an 802.11b mode, CCK TX FIR Override forces a 2x2
radio configuration into 1x for Tx and 2x for Rx (ie 1x2) for
regulatory compliance reasons. Add gEnableCckTxFirOverride to allow
this firmware feature to be enabled/disabled via ini configuration.
