David Woodhouse 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.

Julia Lawall 6a19309db0 drivers/atm: Use DIV_ROUND_UP
The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /
(d)) but is perhaps more readable.

In the case of the file drivers/atm/eni.c, I am a little bit suspicious of
the -1 at the end of the affected expression.  Please check that that is
what is wanted.

An extract of the semantic patch that makes this change is as follows:
