The idea here is to create a structure per set of channels so that we
can define much more than basic bitfields for these.
The structure is currently almost empty on purpose because this change
is supposed to be a mechanical update without additional information but
more details will be added in the following commits.
For each page, the core now has access to how many "chunks" of channels
are defined. Overall up to only 3 chunks have been defined so let's
hardcode this value to simplify a lot the handling. Then, for each
chunk, we define an independent bitfield of channels. As there are
several users of these bitfields, we also create the
cfg802154_get_supported_chans() helper to reconstruct the bitfield as it
was before when the only information that matters is identifying the
supported/unsupported channels.
