Improve 5704S autoneg logic by using a serdes_counter field to keep
track of the transient states. This eliminates a 200 msec busy
loop in the code. Autoneg will take its course without the driver
busy waiting for it to finish.

In case of non-blocking connects it is possible that the last user
of an ACL link quits before the connection has been fully established.
This will lead to a race condition where the internal state of a
connection is closed, but the actual link has been established and is
active. In case of Bluetooth 1.2 and later devices it is possible to
call create connection cancel to abort the connect. For older devices
the disconnect timer will be used to trigger the needed disconnect.

The local version information are needed to identify certain feature
sets of devices. They must be read on device init and stored for later
use. It is also possible to access them through the device model.

In case of non-blocking socket calls we should return EINPROGRESS
and not EAGAIN.
