qcacmn: Add data and constants for frequency offset sign bit

Issue: The offset parameter in bangradar unit test parameter is only one
byte long. Whereas radar offsets has a range of [-160, 80] MHz if host
supports 320 MHz bandwidth. but with bangradar unit test command only till
-128 MHz is possible

To fix this, Add frequnecy offset sign bit(13th bit) if hosts supports
320 MHz bandwidth. Firmware will identify max range of [-160,80] with
sign bit.
