Previously, each bus type was responsible for freeing the firmware
structure, but some did that badly. Move responsibility for freeing
firmware into firmware.c so that it's done once and correctly, instead
of happening in multiple places in bus-specific code.
This fixes a use-after-free bug found by Dr. H. Nikolaus Schaller where
the SDIO code forgot to NULL priv->helper_fw after freeing it.

Do not assume we have our subsystem including this for us,
at least for older kernels this is not true. Lets just be
explicit about this requirement for the usage of wake_up().

Without it, I get compile errors due to missing TASK_NORMAL,
TASK_UNINTERRUPTIBLE and schedule.

As described at
http://article.gmane.org/gmane.linux.kernel.wireless.general/86084
libertas is taking a long time to load because it loads firmware
during module loading.
Add a new API for interface drivers to load their firmware
asynchronously. The same semantics of the firmware table are followed
like before.
Interface drivers will be converted in follow-up patches, then we can
remove the old, synchronous firmware loading function.

Remove the ability to pass module parameters with firmware filenames
for USB and SDIO interfaces.
Remove the ability to pass custom "user" filenames to lbs_get_firmware().
Remove the ability to reprogram internal device memory with a different
firmware from the USB driver (we don't know of any users), and simplify
the OLPC firmware loading quirk to simply placing the OLPC firmware
at the top of the list (we don't know of any users other than OLPC).
Move lbs_get_firmware() into its own file.
These simplifications should have no real-life effect but make the
upcoming transition to asynchronous firmware loading considerably less
painful.
