[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(). Signed-off-by: Marc Zyngier <maz@misterjones.org> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
