qcacmn: Avoid switching to spur channels in UNII-1 band

When operating in 20/40MHz modes in channels 52/56/60/64, spur
is found on adjacent channels (40, 44, 48) if we switch to those
channels after radar. To avoid this issue, add a SW WAR to ignore
selecting the adjacent channels if radar is found on the UNII-2
channels (52-64).
