qcacmn: Disable coex channels in the current_chan_list

The 5G cellular RF band and wifi frequency band of UNII-1
(IEEE channels 36, 40, 44, 48) and UNII-2A band (52, 56,
60, 64) can coexist.

UNII-1 and UNII-2A are represented by bits 0x1 and 0x2 respectively in
this implementation. The user space command should set the bits by
applying the following algorithm:

1) To disable only the UNII-1 band channels, set the value as 0x1.
2) To disable only the UNII-2A band channels, set the value as 0x2.
3) To disable both the UNII-1 and UNII-2A band channels, set the
   value as 0x3.
4) To restore both the UNII-1 and UNII-2A band channels, set the
   value as 0x0.
