amdsmu: Use devclass name instead of module nameHEADmain

The diagnostics array contained expected modules to be loaded but the
checking logic checked for if a devclass of that name existed instead.

Have the diagnostics array contain the devclass instead as well as the
module to load for the hint string.

Furthermore, check tha the number of devices is greater than 0 so that
leftover devclasses from unloaded modules don't skip the hint.
