[ARM] pxa/zeus: make Viper pcmcia support more generic to support Zeus
The Arcom Zeus CF slot requires the same kind of support as the Viper.
To avoid code duplication, introduce a platform device that abstracts
the differences.
This also allows for the removal of the ugly export of viper_cf_rst().
