cc5f7e3976 iwlwifi: implement dynamic opmode loading
This is the next step in splitting up the driver,
making the uCode API dependent pieces of it live
in separate modules. Right now there's only one
so it's not user-selectable, but we're actively
working on more.

75813bde1f iwlwifi: fix memory leak if opmode fails to init
If drv->op_mode is NULL after trying to init the
opmode, we go to the wrong label. Fix this, and
clean up the code a bit.

f6b1154678 iwlwifi: add option to disable 5GHz band
There are various problems happened on 5GHz band not observed on
2.4 GHz (microcode errors, queue stuck, etc... ) . Also roaming
between 5GHz AP and 2GHz does not work very well. To workaround
the problems add option to disable 5GHz support. This will help
on environments where APs are dual-band, and devices will not try
to associate on band where issues happen.

For now at least, all module parameters should be

0479c19d9f iwlwifi: remove uCode alternatives mechanism
We've never released firmware using the alternatives
mechanism and our build process makes that difficult
anyway. This means that in every file we have ever
built (except maybe by hand for testing) the listed
alternative was 0. Make the alternative field in the
TLVs part of the TLV number (thus expanding that to
32 bits); this gives us more TLV numbers (not really
needed) and more importantly protects against rogue
firmware files that actually do use the alternatives
mechanism -- those will now be rejected since they
don't contain any valid TLVs.

0cedacc579 iwlwifi: more modularity in fw images and sections
Changed iwl_firmware_pieces structure to support an array of
separate images, and an array of sections for each image.

In fw_sec and fw_desc structures, added a field for
offset from the HW address, to support 16.0 uCode that
provides an offset instead of any other data about the section.
This field is filled with default values when parsing instruction
or data section.

965974a631 iwlwifi: remove iwl-wifi.h
This file was recently introduced, but then
directly abused -- it contained private data
that shouldn't have been used by anything
but the implementation of firmware requests
and some very core code. Now that it is no
longer accessed by any code but the code in
iwl-drv.c, we can dissolve it.

Also rename the iwl_nic struct to iwl_drv to
better reflect where and how it is used.

0692fe41b3 iwlwifi: split out firmware store
Through the driver, struct iwl_fw will
store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move
the log pointers into it, and remove the
knowledge of "nic" from everything.

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.

Since I wanted to constify the firmware
pointers, some more changes were needed.
