A carrier of an NDI interface is turned on when there is at least one NDI
station that: (1) correlates to this interface (2) is authorized (3) the
NAN peer to which this station belongs has at least one common slot with
the local schedule. Otherwise, it is turned off.
(common slots are slots where both schedules are active on compatible
channels.)
Implement the calculation of the carrier state and trigger it when
needed.

Peer schedules specify which channels the peer is available on and when.
Add support for configuring peer NAN schedules:
- build and store the schedule and maps
- for each channel, make sure that it fits into the capabilities, and
take the minimum between it and the local compatible nan channel.
- configure the driver
Note that the removal of a peer schedule should be done by the driver
upon NMI station removal.

A NAN local schedule consist of a list of NAN channels, and an array
that maps time slots to the channel it is scheduled to (or NULL to indicate
unscheduled).
A NAN channel is the configuration of a channel which is used for NAN
operations. It is a new type of chanctx user (before, the only user is a
link). A NAN channel may not have a chanctx assigned if it is ULWed out.
A NAN channel may or may not be scheduled (for example, user space
may want to prepare the resources before the actual schedule is
configured).
Add management of the NAN local schedule.
Since we introduce a new chanctx user, also adjust the different
for_each_chanctx_user_* macros to visit also the NAN channels and take
those into account.
