Use the BAR value returned by pcidev_init which automatically applies
the correct BAR mask for the drkaiser driver.
Truncate flash chip addresses to fit into the 128 kB memory window for
drkaiser and pick the same window size for gfxnvidia.
Uwe tested all operations successfully on a Dr. Kaiser card.
