Fix #132: Python parser not accepting compute partition arguments

The argparse 'choices' parameter was receiving a comma-separated string
instead of a list, causing it to treat individual characters as valid
choices rather than complete tokens like 'SPX', 'DPX', etc.

Fixed by removing the unnecessary join() operation in
get_accelerator_choices_types_indices() to return the list directly.
This matches the pattern used by get_memory_partition_types().

Now 'amd-smi set -C DPX' and other partition commands work correctly.
