pcmcia: correct handling for Zoomed Video registers in topic.h
Fix handling of Zoomed Video Registers in the Topic pcmcia controller
( http://bugzilla.kernel.org/show_bug.cgi?id=14581 ). The information
has been retrieved from the Topic manual which can be obtained from
Toshiba.
The Zoomed Video is used with PCMCIA Cards like the Margi DVD-to-Go.
