The fmc-chardev module was over-locking, by calling misc
register/unregister while holding its spinlock. This reported a
"scheduling while atomic" error.
Since the misc driver already serializes operations internally, this
commit downgrades the fmc-chardev lock to just cover its own list.

This driver exports the memory area associated with the mezzanine card
as a misc device, so users can access registers.
