Title:
  wifi channel list for China (CN) on 5GHz band is wrong

Status in wireless-regdb package in Ubuntu:
  Opinion

Bug description:
  When I set iw reg to CN, only channels 149 and above are enabled.

  ```
  # iw reg get
  global
  country CN: DFS-FCC
          (2402 - 2482 @ 40), (N/A, 20), (N/A)
          (5170 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW
          (5250 - 5330 @ 80), (N/A, 23), (0 ms), DFS, AUTO-BW
          (5735 - 5835 @ 80), (N/A, 30), (N/A)
          (57240 - 59400 @ 2160), (N/A, 28), (N/A)
          (59400 - 63720 @ 2160), (N/A, 44), (N/A)
          (63720 - 65880 @ 2160), (N/A, 28), (N/A)
  ```

  But this does not match the actual regulations: 
https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_or_5.8_GHz_(802.11a/h/j/n/ac/ax)
  China government allow to use 36, 40, 44, 48, 52, 56, 60, 64 channels for 
many years, see https://en.wikipedia.org/wiki/List_of_WLAN_channels
