 regmap: debugfs: fix race condition in dummy name allocation 
Use IDA instead of a simple counter for generating unique dummy names.
The previous implementation used dummy_index++ which is not atomic,
leading to potential duplicate names when multiple threads call
regmap_debugfs_init() concurrently with name="dummy".
