Recent ath10k-ct 10.1 firmware supports survey results, and
advertises the appropriate service flags.  This confuses
the ath10k driver because the 10.1 wmi commands are not set up
for survey information.  So, this patch adds support for
handling survey information.  Example output:

Survey data from wlan0
	frequency:			5180 MHz [in use]
	noise:				-97 dBm
	channel active time:		44 ms
	channel busy time:		15 ms
	channel receive time:		7 ms
	channel transmit time:		7 ms
Survey data from wlan0
	frequency:			5200 MHz
	noise:				-98 dBm
	channel active time:		46 ms
	channel busy time:		2 ms
...
