Finn Thain e7884eed13 macintosh/adb-iop: Send correct poll command 
[ Upstream commit 10199e90ee20e68859f8128331ec8d85b036d349 ]

The behaviour of the IOP firmware is not well documented but we do know
that IOP message reply data can be used to issue new ADB commands.
Use the message reply to better control autopoll behaviour by sending
a Talk Register 0 command after every ADB response, not unlike the
algorithm in the via-macii driver. This poll command is addressed to
that device which last received a Talk command (explicit or otherwise).
