Firmware sends the following reg rule to build 5G 240MHZ channels
240MHZ reg rule:
start: 5490, end: 5730, max_bw: 240.
However, 240MHZ is not one of the standard IEEE channel width.
Hence the channel finding APIs will fail to find a channel of 240MHZ BW.
240MHZ is considered as a punctured 320MHZ channel (320 - 80).
Hence convert the max bw of 240MHZ reg rule to 320MHZ within the host
so that channel can be built.
Also, change the 5G 240MHZ bonded pair's end freq to 5720. Since there is a
5MHZ bandwidth gap between channel 144 and 149, the bonded pair is
restricted to 5720MHZ on 5G.
