mci: sdhci: atmel: fix truncation when reading out caps

The capability read out was changed a few years ago to use 32-bit
accessors, but the variable that it was stored in remained at 16-bit
leading to truncation of the upper bits and breaking detection of the
SD-Card on my SAMA5D27-SOM1-EK:

  ERROR: barebox-environment chosen:environment-sd.of: probe failed: No such file or directory

Fix this by using the appropriate type. The commit introducing the
regression touched multiple drivers, but the Atmel SDHCI one is the only
one which still used a 16-bit type.
