[PATCH v2 00/23] Support for new regulatory flags and P2P GO channel

The patch add support for the following features:

* Support for channel regulatory flag GO CONCURRENT which allows GO
  instantiation on such a channel even if the channel setting do not allow
  initiating radiation on the channel. A channel marked with the
  GO CONCURRENT flag can be used for GO instantiation iff the device is also
  concurrently connected to BSS on the same channel on the 2 GHz band or to
  a channel in the same UNII band (on the 5 GHz band) and radar is not set.
  The main motivation for this relaxation is that such channels can be used
  for GO operation, since the device is under the guidance of some other
  master device that is assumed to be reliable in the context of regulatory

* In order to prevent daisy chaining scenarios, the above relaxation is not
  allowed when the station interface is connected to a GO. For the similar
  reason, if a GO is instantiated on a channel due to the GO CONCURRENT
  relaxation, it should not allow legacy clients connection to it.

* Add support for changing the P2P GO operating channel (at this point
  without CSA which will be addressed in a different patch set) due to a change
  in the regulatory settings.

* In case that Multi Concurrent Channel (MCC) is supported, add support for
  changing the P2P GO's operating channel due to policy consideration, that
  might prefer operating in single channel mode instead operating in
  multiple channels concurrently.

* To improve the frequency selection during P2P GO channel changes, the patch
  set add support for saving the group common frequencies, and using this
  information when switching a channel, so that the selected frequency/
  channel would be one that can be used by all of the group members.

* Support for INDOOR regulatory flag in the context of P2P. Generally, a
  P2P GO/Client operation on indoor channels is not allowed unless there is
  some knowledge that the device is operating in indoor environment. The
  patch set allows support for using such channels if the peer device is
  identified as a non-mobile device.

* Some utility functions and channel selection modifications.
