qcacmn: Set max BW for each valid channel and send to FW

Configuration for Issue:-
DUT configuration:-
1. Configure DUT's country as US where channel 165 does
not support channel bandwidth of 40 mhz.
AP Configuration:-
1 Configure the AP in a country where channel 165
supports channel bandwidth 40MHZ.
Scenario of the issue:-
1.Connect to a diff AP on some channel x with same SSID,
and then roam to this AP.
Observation:-
The DUT would connect in 40 mhz to this AP instead of 20Mhz,
which violates the DUT's country reg rules.
Expectation:-
The DUT should re-connect only in 20Mhz on channel 165, or
only in max BW supported by reg in that country.
Issue:-
The DUT does not consider the max bandwidth allowed for the channel
in the country configured, and allow the re-association only
in the respective bandwidth.
Fix:-
Send the max BW supported by the channels in the current
reg domain to the FW so that it considers the max BW of the
channel and AP capability and then roam in the respective BW
only.
