In order to fully abstract the bus, we need to save the device
structure *beside* wl1271, instead of inside it.

This will help re-structuring the driver so that we avoid the
duplicated code in the bus modules.

This module has been causing more trouble than being useful.  It only
tests the SDIO speed by connecting to the wl12xx chip and does some
throughput calculations.  It is an ugly quick hack and, if we really
want to have it as part of wl12xx we need to clean it up and implement
it properly.

A tarball of the code has been created and posted here, with some
instructions:

The fw boot and initialization currently happens inside the
add_interface() callback. This is wrong, as add_interface is
called for each new vif. However, we due to some fw limitation
(we have to know the actual mac address on boot), we can't
completely move it into the start() callback.

Until the fw will be fixed, refactor the fw init into
a new function, and call it from add_interface()
