mmc: pxamci: Delete platform data handling of CD and WP
This deletes the code dealing with handling card detect and write protect passed in as platform data and makes the host rely on just GPIO descriptors. The card read only inversion flag has to be kept around for now, as the core cannot handle the inversion flags on the descriptors yet. Since we can now rely on the descriptors to have the right polarity, we set the "override_active_level" to false in mmc_gpiod_request_cd() and mmc_gpiod_request_ro().
