[PATCH v1 8/8] video: cirrusfb: Make use of struct zorro_device_id::driver_data_ptr

[Uwe Kleine-König (The Capable Hub) <u.kleine-koenig@baylibre.com>]

Usage of .driver_data_ptr allows to drop several casts and so make the
driver a bit more type safe.

While touching the zorro_device_id array, drop an unneeded explicit zero
in the list terminator.
