[PATCH] USB: add sl811_cs support

This adds support for a CF-card USB Host adapter, the Ratoc REX-CFU1U, by
wrapping a PCMCIA driver around the existing "sl811-hcd" platform driver.

This CF card is especially useful for PDAs, which currently tend to have
no other solution for USB host capability.
