mmc: core: Announce successful insertion of an SD UHS-II card

Browse Source 
To inform the users about SD UHS-II cards, let's extend the print at card
insertion with a "UHS-II" substring. Within this change, it seems
reasonable to convert from using "ultra high speed" into "UHS-I speed", for
the UHS-I type, as it should makes it more clear.

Note that, the new print for UHS-II cards doesn't include the actual
selected speed mode. Instead, this is going to be added from subsequent
change.
