This is looking very good. Just one more thing and I can commit it
for this release. The AHCI driver can be unloaded... the sysctl
nodes have to be destroyed when it is. It can be done in
ahci_port_free(). Keep in mind that the function can be called
on a partially initialized port so conditionalize the destruction of
the sysctl node on it having been installed.
