mmc: add per device quirk placeholder

Browse source 
Some cards have quirks valid for every platforms using current
platform quirk hooks leads to a lot of code and debug duplication.

So we inspire a bit from what exists in PCI subsystem and do our own
per vendorid/deviceid quirk.  We still drop the complexity of the pci
quirk system (with special section tables, and so on).
That can be added later if needed.
