- Use mutex to serialize index/data register pair usage, when
accessing SATA registers. Unserialized access under heavy load caused
wrong speed reporting and potentially could cause device loss.
- To free memory and other resources (including above), allocated
during chipinit() method call on attach, add new chipdeinit() method,
called during driver detach.
