[PATCH 5/9] mci: core: parse cid into parameters

[Stefan Kerkmann]

To make the MMC/SD CID information accessible for scripting all
available CID fields are added as parameters during device probing. As
some fields have different data types for MMC and SD cards a string
representation is chosen these cases.
