w83627hf/acpi: Fix type error in floppy drive enumeration code

The enumeration method tried to evaluate an one-byte OperationRegion
    instead of a field in this OperationRegion, which resulted in an
    AE_TYPE error at runtime.
    Indexing the OperationRegion with a single field fixes this error.
