The rate scaling and the transport need to access the data in
iwl_tid_data, hence the move.

Note that the only component in the upper layer that needs this data
is the rate scaling. Refactoring the rate scaling may help to move
iwl_tid_data from the shared area to the transport area.

The current firmware loading mechanism in
iwlwifi is very hard to follow, and thus
hard to maintain. To make it easier, make
the firmware loading synchronous.

For now, as a side effect, this removes a
number of retry possibilities we had. It
isn't typical for this to fail, but if it
does happen we restart from scratch which
this also makes easier to do should it be
necessary.

All _agn devices support continuous uCode trace, remove checking
Signed-off-by: NWey-Yi Guy <wey-yi.w.guy@intel.com>

There's no need to keep both normal and BT statistics
versions around all the time in memory when we only
use a subset of both. So keep only the subsets that
we need in memory, depending on the debug config).

Also, in doing so, we can remove all the calls to
iwl_bt_statistics() in the driver as we'll just
access the copied statistics now.

Finally, also remove this call from the one place
where it might still be needed and automatically
detect what kind of statistics the device is sending
based on their size. This way, we don't need to keep
track of which devices do what any more, which is
good since this is subject to change based on the
ucode version (as some ucode even for non-BT devices
will in fact use BT statistics).

Warn upon encountering a statistics command from the
ucode that isn't known, so we will find such issues
earlier in the future.
