wlan: Add new IOCTL to set tx power based on proximity
Add a new IOCTL, setProximity, to set the tx power per band,
based on proximity value. When ioctl is called with value 1,
then driver reads power values from nv.bin and sends the same
to FW. For value 0 driver sends tx power as 50dbm to FW, so that
FW can set max allowed tx power.
