Some drivers (such as iwlmvm) can handle multiple bands in a single
HW scan request. Add a HW flag to indicate that the driver support
this. To hold the required data, create a separate structure for
HW scan request that holds cfg scan request and data about
different parts of the scan IEs.

As this changes the mac80211 API, update all drivers using it to
use the correct new function type/argument.

This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.

Verified by compilation only.

This array is used in debug string to display cw1200_link_status
defined in drivers/net/wireless/cw1200/cw1200.h.

Add missing strings for CW1200_LINK_RESET and CW1200_LINK_RESET_REMAP.

This will allow the low level driver to make decision based
on the vif such as queues etc...
Since the vif might be NULL, we can't add it to the tracing
functions.

Instead of an explicit cast, use the min_t macro.
