accel/ivpu: Fix reset_engine debugfs file logic
The current reset_engine implementation unconditionally resets
all engines. Improve implementation to reset only the engine
requested by the user space to allow more granular testing.
Also use DEFINE_DEBUGFS_ATTRIBUTE() to simplify implementation.
Same changes applied to resume_engine debugfs file for consistency.
