The 160MHz AP mode was not properly working and limited due to lack of
DFS offload. So this series include following changes:

 * encode 160MHz channel definition to firmware format.
 * adapt custom regulatory rule allowing 160MHz.
 * enable DFS offloading for firmwares supporting it.

The series applies to the master branch of the wireless-drivers-next
repository.

  brcmfmac: add 160MHz in chandef_to_chanspec()
  brcmfmac: enable DFS_OFFLOAD extended feature if supported
  brcmfmac: allow 160MHz in custom regulatory rules

The function chandef_to_chanspec() was not handling 160MHz bandwidth
resulting in wrong encoding of the channel. That resulting in firmware
rejecting the provided channel specification.

If the firmware supports 802.11h and the device can operate in 5GHz
band we can enable DFS_OFFLOAD extended feature.

The driver has custom regulatory rules which had maximum bandwidth
for 5GHz channels set to 80MHz. As a consequence the driver can
not use 160MHz in AP mode even when the device supports it. So
relax the rules allowing 160MHz. After wiphy_register() the channel
flags are updated according what the device actually supports.
