qcacld-3.0: Set 5G band capability bit in gActionOUIConnect1x1 ini

Browse Source 
gActionOUIConnect1x1 is used to specify action OUIs for 1x1
connection.

Some Access Points are unable to handle SMPS and OMN frames and shows
abnormal behaviour when STA is switching between 2x2 to 1x1 and
vice-versa. To avoid this, restrict connection in 1x1 mode with such APs.

Here the scenario is DUT STA1 connects in 2x2 mode to AP1 in 5G mode then
later on DUT another STA2 iface connects to AP2 in 2G mode. DUT sends OMN
frame to AP1 to inform that it is going to switch to 1x1 mode. AP1 ack
this frame but doesn't change its Tx rates and continues to use 2x2 rates
which DUT cannot ACK. This causes low throughput issue where AP1 Tx rate
falls to 6Mbps due to missing acks.

Hence, 5G band capability bit in "gActionOUIConnect1x1" is set to make
connections in 1x1 with such AP.

Presently, 5G band capability bit is not checked if 2G band capability bit
is not set or 2G band is not enabled. Hence, Vendor AP capability check for
2G and 5G Band is refactored.
