The as102 driver can be converted to use module_usb_driver() which saves
a lot of code, and gets rid of an unwanted err() call at the same time.

The interface data should not be used as a flag to signal disconnect.

Now that all serial drivers use the usb_serial disconnect flag and
mutex, we can set the interface data prior to registering the ports and
there's no need to clear it at disconnect.

This should hopefully also make it more clear that the interface data is
not a flag, which could prevent future misuse.

The ehci-hcd driver is a little haphazard about keeping track of the
state of the USBCMD register.  The ehci->command field is supposed to
hold the register's value (apart from a few special bits) at all
times, but it isn't maintained properly.

This patch (as1543) cleans up the situation.  It keeps ehci->command
up-to-date, and uses that value rather than reading the register from
the hardware whenever possible.
