Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

that handles PCI device and registers three new devices one per card
reader type. The other driver handles SD/MMC part of the reader.
