clean up wscons frame buffer attachment interface slightly. Make 

ioctl and mmap routines take a void *, rather than a struct device *,
so that they can be set up to work more easily when using a 'struct device *'
isn't appropriate.  Add a cookie (void *) to be passed to the mmap and
ioctl routines.  Rename a few struct members, and shuffle them into
a more sensible order.
