When different images can (soon) be accessed through this
file, storing the section offset/length on first access to
the file breaks (or needs manual reset). Avoid this by not
storing the offset/length values but using them locally in
the function only. That way, the correct values are always
used.

While at it, correct the check that firmware is loaded.

The D3 image SRAM is overwritten by the runtime image, so
it can't be accessed after resume. However, it can be very
useful to look at it to know what happened during D3, so
add the ability to store the image and make it available
in debugfs.

In theory, the firmware format allows changing the data section
offset. This may not be used today, but there's no reason for
the driver to assume the data section is always at 0x800000 as
it can know better.

This allows to have better wifi TPT when BT is active under
good RSSI conditions.
Wifi will have better chance to send Acks and Cts even if BT
is active.

Use the per-interface debugfs infrastructure to create a
directory and symlink, and add a file containing debug
data related to each virtual interface.

This allows to test fw restart flow. The hook in transport
layer doesn't really make the fw assert. Moving this hook
to the op_mode allows to use the fw API to actually send a
host command that will make the fw assert.

Change the restart_fw module parameter to be a boolean on
the way.

replaces file operations references to the function
with simple_open() instead.

Newer firmware revisions have a completely new
firmware API. This is the new driver for this
new API.

I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.
