Venkateswara Naralasetty 720e5c03e5 ath10k: provide survey info as accumulated data 
It is expected that the returned counters by .get_survey are monotonic
increasing. But the data from ath10k gets reset to zero regularly. Channel
active/busy time are then showing incorrect values (less than previous or
sometimes zero) for the currently active channel during successive survey
dump commands.

example:

  $ iw dev wlan0 survey dump
  Survey data from wlan0
  	frequency:                      5180 MHz [in use]
  	channel active time:            54995 ms
  	channel busy time:              432 ms
  	channel receive time:           0 ms
  	channel transmit time:          59 ms
  ...

  $ iw dev wlan0 survey dump
  Survey data from wlan0
  	frequency:                      5180 MHz [in use]
  	channel active time:            32592 ms
  	channel busy time:              254 ms
  	channel receive time:           0 ms
  	channel transmit time:          0 ms
  ...

The correct way to handle this is to use the non-clearing
WMI_BSS_SURVEY_REQ_TYPE_READ wmi_bss_survey_req_type. The firmware will
then accumulate the survey data and handle wrap arounds.
