The vmebus allows to register devices directly by writing a registration
string in a sysfs bus attribute.

There is no need for the VME device driver to register itself the
devices by asking the user to provide module parameters.

Now, all the parameters a given directly to the vmebus.

Also the fw_name module parameter has been removed. The user can use the
char device to re-program the FPGA.

NOTE
* I thought a bit about the fw_name. Users may want to load their
  bitstream immediately before anything else. Is it a real use case?

On spec driver remove, do not clean-up VIC stuff. The VIC should be cleaned
by the mezzanine driver when it release all its handlers (see patch a628fa3).
Just leave a reminder for driver developer when something goes wrong.

Moreove, we do not need to user sver_irq_exit() any more. If the mezzanine
driver is properly written it will clear all its interrupts, and thanks to
patch a628fa3 we can safely assume that everything was cleared.
