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.

In order to let the core derive eg. the symbol duration for a given
channel, it needs to know which protocol is being used, on which band,
and eventually more details such as the mean PRF in the case of UWB.
Create the necessary enumerations to declare all of that. Include them
in the currently-almost-empty phy_channels structure which until now
only declared the supported channels as bitfields.
The PRF is declared in a union as this clearly is a parameter that does
not apply to most of the protocols. It is very likely that other
parameters will get added in the future to further define specific
protocols and the union will likely be a good location for them.

Tdsym is often given in the spec as pretty small numbers in microseconds
and hence was reflected in the code as symbol_duration and was stored as
a u8. Actually, for UWB PHYs, the symbol duration is given in
nanoseconds and are as precise as picoseconds. In order to handle better
these PHYs, change the type of symbol_duration to u32 and store this
value in nanoseconds.
All the users of this variable are updated in a mechanical change.

Now that we have access to all the basic information to know which
symbol duration should be applied, let's set the symbol duration
automatically. The two locations that must call for the symbol duration
to be set are:
- when manually requesting a channel change though the netlink interface
- at PHY creation, ieee802154_alloc_hw() already calls
ieee802154_change_channel() which will now update the symbol duration
accordingly.
If an information is missing, the symbol duration is not touched, a
debug message is eventually printed. This keeps the compatibility with
the unconverted drivers for which it was too complicated for me to find
their precise information. If they initially provided a symbol duration,
it would be kept. If they don't, the symbol duration value is left
untouched.

The core now knows how to set the symbol duration in a few cases, when
drivers correctly advertise the protocols used on each channel. For
these drivers, there is no more need to bother with symbol duration,
lifs and sifs periods so just drop the duplicated code.
