PHY settings for QCA9377-3 based module

[Bryce Allen]

Use the "iw" command as root, something like this, assuming 'wlan0' is 
the device name. To figure out your wireless device name, you can do 'ip 
link' to see a list of interfaces and the wireless one should be pretty 
obvious.

# get current txpower
$ iw dev wlan0 info | grep txpower
      txpower 22.00 dBm

# set
$ iw dev wlan0 set txpower fixed 2000
$ iw dev wlan0 info | grep txpower
      txpower  20.00 dBm

# set back to auto
$ iw dev wlan0 set txpower auto

Note that increasing txpower may be limited by local regulations, `iw 
reg get` will show current region. There are region free patches 
floating around.

Note the confusing difference in units for display (dBm), and setting 
(mBm), factor of 100 difference for some reason?
