01e2ffac7d solos: Handle attribute show/store in kernel more sanely
There are still a _lot_ of attributes, but for at least the basic ones
we want to be able to get/set them from the kernel. Especially the ones
we want to inform the ATM core about (link state, speed).

fa755b9f2b solos: Clean up firmware loading code
We no longer try to load firmware while the ATM is up and running.
However, this means that we _do_ make init_module() wait for it, and it
takes a long time for now (since we're using ultra-conservative code in
the FPGA for that too).

The inner loop which uses swahb32p() was by Simon Farnsworth.

Simon has patches which migrate us to request_firmware_nowait(), for
which we'll actually need to take down the ATM devices, do the upgrade,
then reregister them.

4306cad6fe solos: Slight debugging improvements
Print a message if pskb_expand_head fails.

Make atmdebug writable by root, so that you can turn printing of data sent to
and received from the card on and off at runtime - useful for tracking
corruption.
